A researcher wants to test if the mean price of houses in an area is greater than $145,000. A random sample of 35 houses selected from the area produces a mean price of $149,700. Assume that O=$13,100, and that the test is to be made at the 1% significance level. a. What is the critical value of z? A) 1.88 B) 2.17 C) 1.96 D) 2.58 b. What is the value of the test statistic, z, rounded to three decimal places? c. What is the p-value for this hypothesis test, rounded to four decimal places? d. Should you reject or fail to reject the null hypothesis in this test? (State your answer as "reject" or "fail to reject", but don't include the quotation marks.)
