I need the correct answer for b.

An article in the San Jose Mercury News stated that students in the California state university system take 5.5 years, on average, to finish their undergraduate degrees. A freshman student believes that the mean time is less and conducts a survey of 60 students. The student obtains a sample mean of 4.9 with a sample standard deviation of 0.8. Is there sufficient evidence to support the student's claim at an a = 0.05 significance level? Preliminary: a. Is it safe to assume that n ≤ 5 % of all college students in the local area? No Yes b. Is n 30 ? Yes ४ го о No Test the claim: a. Determine the null and alternative hypotheses. Enter correct symbol and value. Ho: μ = Ha: µ< 5.5 5.5 b. Determine the test statistic. Round to four decimal places. t X = 5.8095 c. Find the p-value. Round to 4 decimals. p-value = 0.0000
