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 10 days,chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below.345 6789 10DayStore 1Store 2Difference(Store 1 - Store 2)Send data to calculatorCheck1454381732446808 975404 835275754 34142 -27 221 -663997809 246 263 703336 759(a) State the null hypothesis H and the alternative hypothesis H₁.HOH₁:0(b) Determine the type of test statistic to use.Type of test statistic: Chi-Square63 50300 214 734Based on these data, can the owner conclude, at the 0.10 level of significance, that the mean daily sales of the two stores differ?

+ 2 E I A Read aloud Draw Highlight Erase 26. The student senate at a local university is about to hold elections. 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.…
Inferential Statistics Are the M&M’s weights accurate? According to the package, each small bag of peanut M&M’s should weigh 49.3 grams. To determine if the bag weights are on target, use the weight of the bags of M&M’s and conduct a hypothesis test to see if the company’s claim is true. Using α = .05 and the five-step process, be sure to include your hypotheses and work. Calculate the corresponding confidence interval for the mean of the weights. Does your results and decision in this problem match the decision you made in Problem 5? Is the average number of orange M&M’s in a bag different from the average number of brown M&M’s? Conduct a hypothesis test at the α = .05 level to answer that question. The following data set includes information from 30 bags of M&M’s. For each bag, the count for each color is provided as well as the bag’s weight prior to it being open. Bag # Red Green Blue Orange Yellow Brown Weight 1…
