Students in a statistics class at Penn State were asked, “About how many minutes do you typically exercise in a week?" Responses from the women in the class were as follows: 60, 240, 0, 360, 450, 200, 100, 70, 240, 0, 60, 360, 180, 300, 0, 270 Responses from the men in the class were as follows: 180, 300, 60, 480, 0, 90, 300, 14, 600, 360, 120, 0, 240 1. What assumptions or conditions are required if conclusions are to be made about amount of exercise for the population of all Penn State students on the basis of these sample results? 2. Assume that the conditions are met, and conduct a test to determine whether the mean amoun of exercise differs for men and women. This is an independent samples t-test. Do not assume variances are equal so use the unpooled formula. Specify the value of a that you chose to use. Report your t-test result in APA format: t(df) = ,p< .05 (or p > .05 if appropriate)

Use the following for the next two questions: The Hershey Company wants to know if it is doing better in the US than its biggest competitor, Nestle, during their biggest sales month of October. A random sample of 50 US grocery stores are chosen and their October, 2020 sales records are collected. Let ???? and ???? be the true average sales in millions of dollars of Hershey and Nestle products sold in US grocery stores during October, 2020 respectively. The 95% confidence interval for ???? − ???? from our sample data is (54, 346) millions of dollars   What is the difference in the sample means ??̅?? − ??̅??? Round to the nearest whole number. 200

Can you please help with all 3 parts of this question: To test for a relationship between gender and souvenir shopping, a survey of more than 2,000 tourists was conducted. One question asked how often a tourist purchases photographs, postcards, or paintings of the region visited. Responses were recorded as “always”, “often”, “occasionally”, or “rarely or never”. The table shows the number of tourists responding in each category by gender.   Male Female Aways 275 445 Often 420 500 Occasionally 390 425 Rarely or never 305 230 a. Give the marginal distribution of responses. b. Give the conditional distribution of responses for each gender. Do you think there is a relationship between gender and souvenir purchase frequency? c. Test for a relationship between gender and souvenir purchase frequency at a significance level of 0.1.
