Reconsider Dr. Sameer's research question about how much time Cal Poly students spend on watching television. Dr. Sameer surveys a random sample of 100 Cal Poly students and finds that the mean number of hours per day watching TV turns out to be 3.0 hours. Suppose that to answer the research question Dr. Sameer conducted a simulation under the null hypothesis. The plot below shows the null distribution with a total of 150 simulated samples (Tip: note that I did not run 1000 simulated samples here!).  The mean of the null distribution is 2.79  The standard deviation of the null distribution is 1.6. -Calculate and report the p-value from

A researcher takes sample temperatures in Fahrenheit of 16 days from San Francisco (Group 1) and 22 days from Atlanta (Group 2). Test the claim that the mean temperature in San Francisco is less than the mean temperature in Atlanta. Use a significance level of a = 0.10. Assume the populations are approximately normally distributed with unequal variances. You obtain the following two samples of data. Round answers to 4 decimal places. San Francisco 77.4 94.8 77 80.9 84 Ho: M₁ 73.4 84.9 92 60.6 83.6 92.5 76.3 93.4 87.2 81.5 70.4 What are the correct hypotheses? Note this may view better in full screen mode. Select the correct symbols for each of the 6 spaces. Atlanta 85.4 92.8 80.2 87.9 80.6 77.9 72.9 75.9 72.1 76.7 80.4 92.5 75.9 72.1 97.7 89.2 88.1 80 92.2 86 96.2 91.9 p-value H₁: M₁ Based on the hypotheses, find the following: Test Statistic = -0.635 X = 0.2494 × OH₂ The p-value is greater than alpha OF H₂ to alpha. The correct decision is to fail to reject the null hypothesis or The…

The following information is available for two samples selected from independent normally distributed populations.   Population​ A:    n1=30    S2/1=25   Population​ B:    n2=30    S2/2=36     a. Which sample variance do you place in the numerator of FSTAT​?   b. What is the value of FSTAT​?
