Assignment Questions

The answers to questions 1-3 must include

what data you used (inclusion / exclusion)
and selection of appropriate statistical measures and why,
an appropriate presentation of the data in a graph and / or table,
statements about assumption testing, and
an appropriate conclusion based on a statistical test, with justification in text.

Report the p-value to 2 or 3 decimal places (p=0.02, p<0.001, p=0.008 for example) and other values to 2 decimal places. There will be penalties for going over specified word and page limits.

QUESTIONS 1-3

Analysis questions using HINTS data

These analyses require using several variables from the HINTS4 Cycle 2 data set and assessing the relationship of several variables. In particular, you will be testing the relationships of BMI, both as a continuous variable (provided) or as a categorical variable, which will need to be constructed, and several other variables of interest. Variable names are in brackets and their details may be found in the codebook.

Max 5 pages to answer questions 1-3

QUESTION 1

Consider body mass index BMI (bmi) as a continuous variable. Use hours of watching television or playing computer games (AverageDailyTVGames) in hours per day as a continuous variable to predict BMI. Comment on the similarity or otherwise of the relationship between men and women. Gender is (genderc).

QUESTION 2

Consider BMI (bmi) as a continuous variable. Is BMI related to annual income (IncomeRanges) when income is considered to be 4 categories (“$0 to $34,999”, “$35,000 to $99,999”, “$100,000 to $199,999” and “$200,000 and above”)? Comment on the similarity or otherwise of the relationship between men and women.

QUESTION 3

For both men and women, underweight is BMI < 18.5; healthy weight is BMI >= 18.5 to <25; overweight is BMI > = 25 to <30; obese is BMI > = 30. Construct a categorical variable with these categories from the continuous variable BMI (bmi). Analyse the relationship between the BMI categorical variable and Income variable with four categories used in Question 2. Interpret your findings

QUESTION 4

Write 200 words describing your overall conclusions from the above analyses in Questions 1-3. Comment on the findings. (Essentially a summary of Qs 1-3).

QUESTION 5

Write an analysis plan to examine the relationships between several variables from the HINTS4 Cycle 2 participants’ with their reported age using the age variable is in 5 categories (AgeGrpB). Consider age group in relation to several other variables, namely, gender (genderc), education (Education), using the internet to look up cancer information (InternetCancerInfoSelf) and BMI category as defined in Question 3. Finally, include a brief analysis plan to relate one sleep pattern variable, which is the hours per working day (SleepWorkdayHr), with continuous BMI (bmi). Use the same PDF codebook as for Questions 1 to 4. This is available in attached documents.

3.1

Which of these data sets has a higher mean? Higher median? Higher standard deviation? (Do not do any calculations. Just look at the data.)

3.2

Which of these data sets has a higher mean? Higher median? Higher standard deviation? (Do not do any calculations. Just look at the data.)

3.9

Suppose that you have 10 observations that have a mean of 7, a median of 6, and a standard deviation of 3. If you double the value of each observation, what are the new values of the:

Mean?
Median?
Standard deviation?

3.10

Suppose that you have 10 observations that have a mean of 7, a median of 6, and a standard deviation of 3. If you halve the value of each observation, what are the new values of the:

Mean?
Median?
Standard deviation?

3.11

Identify the apparent statistical mistake in this commentary [13]:

The median cost of a house in [Duarte, California] is a whopping $4,276,462, making it the most expensive housing market in the country. It ranks No. 1 on Forbes’ annual ranking of America’s Most Expensive ZIP Codes.. [O]nly 12 homes are currently on the market. So a single high-priced listing (like the mammoth nine-bedroom, built this year, that’s selling for $19.8 million) is enough to skew the median price skyward.

3.20

Table 1.4 shows the US dollar prices of Big Mac hamburgers in 20 countries. Use a boxplot to summarize these data.

3.21

Figure 3.11 shows two boxplots. Which data set has the higher median? The higher standard deviation?

3.22

Figure 3.12 shows two boxplots. Which data set has the higher median? The higher mean? The higher standard deviation?

3.31

Use the data in Exercise 3.29 to make a scatter diagram with the P/E ratio on the horizontal axis and the return on the vertical axis. Does there appear to be a positive relationship, negative relationship, or essentially no relationship?

3.34

Explain the error in the conclusion reached by a security analyst [16]:

The Dow Jones Industrial Average peaked at 381.17 during September 3, 1929. The so-called Great Crash pushed this index down 48% by November 13. But, by April 17, 1930, the index rebounded 48% from the November bottom. In other words, anyone who bought a diversified portfolio of stocks during September 1929 would have experienced no net change in the value of his portfolio by April of 1930.

3.41

Use the data in Table 3.2 to determine the percentage annual rate of increase in the CPI between 1990 and 2014.

3.42

A 1989 radio commercial claimed: “If you have a LifeAlert security system, your chances of becoming a victim of a serious crime are 3000 to 4000 percent less than your neighbor’s.” Is this possible?

3.43

Twelve college women and men were asked to read a short article and, when they were finished, estimate how long it took them to read the article. Table 3.7 shows the actual and estimated times (both in seconds) and the percentage difference between the two. Summarize the percentage error data with two side-by-side boxplots, one for women and one for men.

3.47

The data in Table 3.10 were used in the 1964 Surgeon General’s Report warning of the health risks associated with smoking, where the first variable is annual per capita cigarette consumption and the second variable is deaths from coronary heart disease per 100,000 persons aged 35 to 64. Calculate the correlation. Does the value of the correlation suggest that there is a positive relationship, negative relationship, or essentially no relationship between cigarette consumption and heart disease?

3.49

If y ¼ 10 – 3x, then the correlation between x and y is:

1.
0.
1.
Undefined.

3.50

Explain how the following two newspaper headlines that appeared on the sameday could both be accurate: “Orders for Machine Tools Increased 45.5% inOctober” [19]; “October Orders for Machine Tools Decreased 29%” [20].

This course has introduced and assessed many noteworthy figures related to the continuing buildup of the United States and its place within the world and globalization during the last 140 years. For this assignment, you will choose an influential civil rights figure from the mid-20th century to the present. Your selection may be taken from speakers or religious, economic, or social leaders. You may not use any U.S. President. This assignment is open to any reform discussed in this course (e.g., creed, race, age, status, or gender).

Prepare an outline communicating that figure’s relevance in today’s modern era. Why and how is this figure important today? This is not a biography. Your argument should highlight how society remembers him or her now.

For this assignment, you will be creating a one-page outline (minimum of 300 words) about your chosen figure. If you choose, this could be used to help write your transcript for the Unit VII assignment described below. Submit your outline in this unit. It is suggested, though not required, that you include potential sources.

The goal of this assignment is to prepare you for the Unit VII assignment described below. However, it is not required that you use the same person from your Unit VI Outline for the Unit VII Scholarly Activity. If you do intend to use this outline in Unit VII, it is highly advised that you review the instructions below and prepare with that assignment in mind.
