She takes a random sample of 100 college students in her area and determines the mean student-loan debt is $27,524 and the standard deviation is $6,000. Is there sufficient evidence to support the student's claim at a 5% significance level? Preliminary: a. Is it safe to assume that n < 5% of all college students in the local area? O Yes No b. Is n 2 30 ? O Yes No Test the claim: a. Determine the null and alternative hypotheses. Enter correct symbol and value. Ho: H Ha: µ ? V b. Determine the test statistic. Round to two decimals. t = c. Find the p-value. Round to 4 decimals. p-value = %3D d. Make a decision. Reject the null hypothesis. Fail to reject the null hypothesis. e. Write the conclusion. There is not sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.
