Use R software to answer the following question. Show the R code.1. Use acceptance-rejection method to set up a function to generate samples from a distribution with pdf of f2(x) with support, [0,1]. 2. Plot the samples you created and add line of the expected distribution to the plot3. Use Monte Carlo integration to estimate the value of the integral using calculate the mean.4. Use Monte Carlo integral to estimate the same integral, but this time utilizing the sampler you created in Problem 2. (hint: don’t sample from the uniform distribution)5. Compare the estimated variance of the estimates generated by the Acceptance-rejection and Monte Carlo integration with 1000 replicates and generate an estimate of the 95% confidence intervals.

3-81. A large farm cooperative in North Dakota owns and leases prime farmland in the upper Midwest. Most of its 34,000 acres are planted in grain. The cooperative performs a substantial amount of testing to determine what seed types produce the greatest yields. Recently, the cooperative tested three types of corn seed on test plots. The following values were observed after the first test year: Seed Type A Seed Type B Seed Type C Mean Bushels/Acre 88 56 100 Standard Deviation 25 15 16 Based on the results of this testing, which seed seems to produce the greatest average yield per acre? Comment on the type of testing controls that should have been used to make this study valid. Suppose the company is interested in consistency. Which seed type shows the least relative variability? Assuming the Empirical Rule applies, describe the production distribution for each of the three seed types. Suppose you were a farmer and had to obtain at least 135 bushels per acre to escape bankruptcy. Which seed type would you plant? Explain your choice. Rework your answer to part d assuming the farmer needed 115 bushels per acre instead.

1. A STAT 200 instructor wants to know if students tend to score differently on the first and second midterm exams. Data were collected from a representative sample of 80 students during the Spring 2018 semester. Data were paired by student. The mean difference, computed as Midterm 1 – Midterm 2, was 5.2076 points with a standard deviation of 5.8854 points. [29 points: A, D, E worth 3 points each; B, C worth 10 points each (2 points per step)]A. Explain why it is appropriate to use the t distribution to approximate the sampling distribution in this scenario.B. Use Minitab Express to conduct a paired means t test to determine if there is evidence that scores on the two exams are different in the population of all STAT 200 students. Use the five-step hypothesis testing procedure given below. Step 1: Check assumptions and write hypothesesStep 2: Calculate the test statisticStep 3: Determine the p valueStep 4: Decide between the null and alternative hypothesesStep 5: State a “real world” conclusionC. Use Minitab Express to conduct a single sample mean t test given a sample size of 80, sample mean of 5.2076, and sample standard deviation of 5.8854 to determine if there is evidence that the population mean is different from 0. Use the five-step hypothesis testing procedure given below. Remember to include all relevant Minitab Express output.Step 1: Check assumptions and write hypothesesStep 2: Calculate the test statisticStep 3: Determine the p valueStep 4: Decide between the null and alternative hypothesesStep 5: State a “real world” conclusionD. Explain why your test statistic and p value were the same in parts B and C.E. What minimum sample size would be necessary to construct a 95% confidence interval for the mean difference in exam scores with a margin of error of 0.5 points? You will need to do hand calculations. Show all of your work. 2. Data concerning employment status were collected from a sample of 100 World Campus students at the beginning of the Fall 2018 semester. In that sample of 100, 67 were employed full-time. [19 points: A, B, C worth 3 points each; D worth 10 points (2 points each step)]A. We want use these data to construct a 95% confidence interval to estimate the proportion of all World Campus students who are employed full-time. Is it appropriate to use the normal approximation method? Show how you checked assumptions. B. Use Minitab Express to construct a 95% confidence interval to estimate the proportion of all World Campus students who are employed full-time. If assumptions were met in part A, use the normal approximation method. Remember to include all relevant Minitab Express output and to clearly identify your answer. C. What sample size would be necessary to construct a 95% confidence interval to estimate the proportion of all World Campus students who are employed full-time with a margin of error of 5%? You will need to do hand calculations. Show all of your work. D. We want to know if there is evidence that in the population of all World Campus students, more than 60% are employed full-time. Use Minitab Express and the five-step hypothesis testing procedure given below. Remember to include all relevant Minitab Express output. Step 1: Check assumptions and write hypothesesStep 2: Calculate the test statisticStep 3: Determine the p valueStep 4: Decide between the null and alternative hypothesesStep 5: State a “real world” conclusion

Tarnita’s Termites, Pacific Lampreys, and Large Brains

“Tarnita’s Termites, Pacific Lampreys, and Large Brains”

For your primary post, please respond to one of the following three topics with a post of at least 125 words that addresses each point given in the instructions. Also, please reply to at least one fellow student on any topic.

Topic 1 : Population Distribution of Termites in a Savanna. Watch the video (1) describing Corina Tarnita’s research on the spacing of termite mounds in savanna ecosystems, and then address the following:

(a) What were Tarnita’s findings about the spacing of termite mounds?

(b) What does Tarnita think is the main factor that governs the spatial distribution of the termite mounds?

(c) How do the termite mounds benefit other organisms on the savanna?

Topic 2 : Pacific Lampreys. Watch the video about Pacific Lampreys (2)*, then address the following:

(a) Where do Pacific lampreys fall in the taxonomy of vertebrates?

(b) What challenges do Pacific lamprey populations face?

(c) Why are Native American tribes of the Northwest concerned about them? (Please note: take care not to confuse the Pacific lamprey (described in the video) with the Sea Lamprey, which is a completely different species that is considered an invasive species in the Great Lakes).

Topic 3 [article]: Supporting the Energy Needs of a Large Brain. As discussed in the article by Zimmer (3)*, brain tissue is energetically expensive. For a species to evolve a large brain, it may need to make certain adjustments to ensure that enough energy is available to support brain function. Zimmer discusses various hypotheses about such adjustments in the human line of descent. Explain one of these adjustments.
