The trend of thinner Miss America winners has generated charges that the contest encourages unhealthy diet habits among young women. Listed below are body mass indexes (BMIs) for Miss American winners from two different time periods. Consider the listed values to be simple random samples selected from larger populations. Using a .05 significance level, test the claim that recent winners have a lower mean BMI than winners from the 1920s and 1930s. Set up your data file so ‘20s and ‘30s winners = 1; recent winners = 2;. BMI (from the 1920s and 30s): 20.4 21.9 22.1 22.3 20.3 18.8 18.9 19.4 18.4 19.1 BMI (from recent winners): 19.5 20.3 19.6 20.2 17.8 17.9 19.1 18.8 17.6 16.8

A company wants to assess the average time it takes for customers to complete a particular task on their website. They collect the following data from a sample of 10 customers: 5, 6, 7, 8, 9, 10, 10, 11, 12, 13 minutes. Calculate the sample mean and standard deviation for this data.
A local convenience store in a large city closes each day at 10 P.M. The owner of the store is investigating whether mean sales will increase by at least $10 per day if the store remains open until 11 P.M. The owner asked the 41 members of a local civic group to estimate the amount of money they might spend during the extra hour. The sample mean was $11.50. The owner will conduct a one-sample tt-test for a population mean. Have the conditions for inference been met? A)nYes, all conditions have been met. B) No, the sample was not chosen using a random method. C) No, the sample size is greater than 10 percent of the population. D) No, the sample size is not large enough to assume normality of the sampling distribution. E) No, the distribution of the sample is not normal.
Scientists measured the amount of drug in tablets produced at two different, independent sites. Scientists want to know whether there is any difference between the mean drug concentration in tablets produced at Site 1 and Site 2. Run the appropriate test in Excel, assuming the population variances are equal. Use an a = .05 significance level. Submit the...
