6. Suppose you are testing Ho: p = 0.64 versus H₁: p < 0.64 where n = 25. From your data, you calculate your test statistic value as +1.1. (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 0.084, what decision should you make (Reject Ho or Do Not Reject Ho)?
