Extracted text: 7. Suppose you are testing Но: и — 62 H1: µ + 62 versus where o? is unknown and n = 14. The data come from a normal population. From your data, you calculate your test statistic value as -2.483. (a) Should you use z or t when finding a p-value for this scenario? (b) Calculate the p-value for this scenario. (c) What is the smallest level of significance (a value) such that we Reject Họ in this scenario?
