Hello, please help!! thanks!!

part 1

How much money do winners go home with from the television quiz show Jeopardy? To determine an answer, a random sample of winners was drawn and the amount of money each won was recorded and listed below. Estimate with 92% confidence the mean winning's for all the show's players. 33152 34129 48867 32287 46393 43533 36091 30116 34945 47721 48188 38778 38452 35900 37890 UCL = LCL = (1 point) Randomly selected 20 student cars (population 1) have ages with a mean of 7.7 years and a standard deviation of 3.4 years, while randomly selected 22 faculty cars (population 2) have ages with a mean of 5.6 years and a standard deviation of 3.7 years. (For the purposes of this exercise, the two populations are assumed to be normally distributed.) 1. Use a 0.05 significance level to test the claim that student cars are older than faculty cars. The test statistic is An alternative method to that done in class uses n1+n2-2 degrees-of-freedom instead of the minimum of n1-1 and n21. Using this approach, find the Pvalue: Is there sufficient evidence to support the claim that student cars are older than faculty cars? 0 A. Yes Q B. No 2. Construct a 95% confidence interval estimate of the difference #1 [12: where #1 is the mean age of student cars and [42 is the mean age of faculty cars. (Use the using the n1+n2-2 degrees-offreedom formula).
