You wish to test out the fairness of a coin at a significance level of a = 0.01. You obtain a sample of size 589 in which there are 287 heads, leading you to believe that the proportion of heads is different from 0.5. With hypotheses Ho:p = 0.5 vs H1:p# 0.5, what is/are the critical value(s)? (Report answer accurate to 2 decimal places.) II 土 What is the test statistic for this sample? (Report answer accurate to 2 decimal places but do not round in the middle of your calculations.) What is the p-value for this sample? (Report answer accurate to 4 decimal places.)
