D Question 9 1 pts What is the test statistic? (If it is z, round to two decimals; if it is t, round to three decimals) O ttest = -0.529 O ttest =-0.035 O Ztest = -1.73 O ttest = -1.733 D Question 10 1 pts What is the p-value? O =t.dist(-1.733, 49, TRUE) O 0.0418 O =t.dist(-0.035, 49, TRUE) O =t.dist(-0.529, 49, TRUE) Question 11 1 ntsFor questions 6 through 13, refer to the following problem: Closing costs for mortgages are an important concern for people buying homes. A realtor read an article in an industry publication that stated the mean closing costs for single-family homes in Michigan were $1958. She suspected that closing costs in her county were lower than that. To test this, the realtor took a random sample of 50 single-family home sales in her county. In the sample, the mean closing costs were $1832 and the standard deviation was $514. Perform a hypothesis test to determine whether the population mean closing costs in the realtor's county are lower than the mean in Michigan as a whole. Use an a = 0.05 significance level. What are the mean closing costs in the sample? O T = 1958 O T = 1832 OH = 1832 Or = 514 Question 7 1 pts1 pts D Question 7 o is [ Select ] D Question 8 1 pts What are the correct hypotheses to use here?
