A statistics student asked students with jobs how many times they went out to eat in the last week. There were 25 students who had part-time jobs and 25 students who had full-time jobs. Carry outa hypothesis test to determine whether the mean number of meals out per week for students with full-time jobs is greater than that for those with part-time jobs. Use a significance level of 0.01.Assume that the conditions for a two-sample t-test hold.Full-time jobs:7, 2, 6, 3, 5, 4, 5, 7, 1, 6, 6, 2, 2, 5, 3, 7, 7, 7, 6, 4, 7, 1, 3, 4, 3 DPart-time jobs:4, 7, 4, 6, 6, 1, 1, 7, 1, 1, 3, 4, 4, 6, 6, 3, 3, 1, 6, 4, 1, 7, 7, 1, 1Determine the hypotheses for this test. Let HET be the population mean number of times students with full-time jobs eat out during a week, and let Hpt be the population mean number of timesstudents with part-time jobs eat out during a week.Ho: HFT - HPT= 0Ha: HFT - HPT> 0Find the test statistic for this test.t =(Round to two decimal places as needed.)
