Use the data file DentistOfficeBills. sav. This data represents a simple random sample of dental bills at a dentist office in Idaho Falls and a dentist office in Rexburg. Let μ1 be the mean bill at the Idaho Falls office, and let μ2 be the mean bill at the Rexburg office. Perform a hypothesis test to determine if the mean bill at the Idaho Falls office is less than the mean bill at the Rexburg office, which means we have the null hypothesis H0:μ1=μ2 and alternative hypothesis H0:μ1<μ2. Use the level of significance α=0.10What is the degrees of freedom? (Round to three decimal places)What is the sample standard deviation for Rexburg? (Round to three decimal places)What is the test statistic? (Round to three decimal places)What is the P-value? (Round to three decimal places.)What is the correct decision based on this evidence? Reject the null hypothesis or Fail to reject the null hypothesis. Suppose instead that you had used the alternative hypothesis Ha:μ1≠μ2 . What is the correct decision based on this evidence? a) We have sufficient evidence that the mean dentist bills between the two cities are different. b) We have insufficient evidence that the mean dentist bills between the two cities are different. c) We have sufficient evidence that the mean dentist bills between the two cities are the same. d) We have insufficient evidence that the mean dentist bills between the two cities are the same.
