College tuition: The mean annual tuition and fees in the 2013-2014 academic year for a sample of 13 private colleges in California was $39,000 with a standard deviation of $7200. A dotplot shows that it is reasonable to assume that the population is approximately normal. Can you conclude that the mean tuition and fees for private institutions in California is greater than $35,000? Use the a=0.10 level of signicance and the P-value method with the TI-84 Plus calculator. State the appropriate null and alternate hypotheses. H0: H1: This hypothesis test is a test. Alternate Answer: H0: p: 35,000 H1 : p> 35,000 This hypothesis test is a right-tailed test. Compute the Pvalue. Round the Pvalue to at least four decimal places. P-value=- Determine whether to reject H0. (Choose one) v the null hypothesis Ho- Rejett Good credit: The Fair Isaac Corporation (FICO) credit score is used by banks and other lenders to determine whether someone is a good credit risk. Scores range from 300 to 850, with a score of 720 or more indicating that a person is a very good credit risk. An economist wants to determine whether the mean FICO score is lower than the cutoff of 720. She nds that a random sample of 55 people had a mean FICO score of 685 with a standard deviation of 80. Can the economist conclude that the mean FICO score ls less than 720? Use the a=0.10 level of signicance and the P-value method with the Tl-84 Plus calculator: State the appropriate null and alternate hypotheses. Ho: p = 720 H]: u
