Suppose that in a sample of 100 college students in Illinois, the mean credit card debt was $377 and the standard deviation was $106. Suppose that we also have reason to believe (from previous studies) that the population standard deviation of credit card debts for this group is $125. Use this information to calculate a 99% confidence interval for the mean credit card debt of all college students in Illinois. Round all answers to the nearest hundredth. (a) = 377 (b) s = 106 (C) o = 125 (d) n = 100 OP Enter DNE if this is unknown. Enter DNE if this is unknown. (e) Critical Value z (f) Find the 99% confidence interval and complete the sentence below. ✓ ✓= Conclusion: We estimate with 99 Illinois, is between S and S % confidence that the mean credit card debt of all college students in
