2. Suppose you are testing Но: р — 0.8 H1: p < 0.8, versus where n = 25. From your data, you calculate your test statistic value as +1.2. (a) Should you use z or t when finding a p-value for this scenario? (b) Calculate the p-value for this scenario. (c) Using a significance level of 0.062, what decision should you make (Reject Ho or Do Not Reject Ho)?
