The average student-loan debt is reported to be $25,235 with a population standard deviation of $6000. A student believes that the student-loan debt is higher than 25,235 in her area. She takes a random sample of 100 college students in her area and determines the mean student-loan debt is 27889. Use the Classical Method (compare the test statistic with the Z-critical value) to determine if there is sufficient evidence to support the student's claim at a 5% significance level? Ho: 4-$25,235 Haμ>$25,235 a. Determine the test statistic. Round to 3 decimals. z= b. Find the critical value for z. Round to 3 decimals. Z-crit- c. Make a decision. O Reject the null hypothesis since the z-score for the data is greater than the Z-critical value. Fail to reject the null hypothesis since the z-score for the data is NOT greater than Z-critical value. d. Write the conclusion. O There is not sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area. O There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area. Question Help: Video Submit Question
