Sales can vary considerably dependingon the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 8 days,chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.Day12345678Store 1878511 837835755241 713443DStore 2685 412 785763480173639287Difference(Store 1 - Store 2)193 9952722756874156Send data to calculator VBased on these data, can the owner conclude, at the 0.05 level of significance, that the mean daily sales of the two stores differ? Answer this question byperforming a hypothesis test regarding μ (which is u with a letter "d" subscript), the population mean daily sales difference between the two stores. Assumethat this population of differences (Store 1 minus Store 2) is normally distributed.Perform a two-tailed test. Then complete the parts below.

English Air continually monitors the proportion of overweight items checked by passengers on its flights in order to evaluate the appropriateness of their overweight fees. Recently, a random sample of 258 items checked on English Air flights to North America contained 48 overweight items, and an independent, random sample of 235 items checked on English Air flights within Europe contained 26 overweight items. Based on these samples, can we conclude, at the 0.10 level of significance, that there is a difference between the proportion p₁ of all items on English Air flights to North America that are overweight and the proportion p of all items on English Air flights within Europe that are overweight?

A representative from the women's sports program and a representative from the men's sports program must both be elected. Two candidates, an incumbent and a challenger, are vying for each position and early polling results are presented next. A hypothesis test must be performed to determine whether the percentages of supportipg votes are different between the two incumbent candidates. In a sample of 100voters, 67 said that they would vote for the women's incumbent candidate. In a separate sample of 100 voters, 55 said they would vote for the men's incumbent candidate. Let p1 and p2 be the proportions of supporting votes for the incumbent candidates representing women's and men's sports programs, respectively. Which of the following are the competing hypotheses to determine whether the percentages of supporting votes are different between the two incumbent candidates? А.…
