Suppose a random sample of 100 observations from a binomial population gives a value of p = 0.72 and researchers wish to test the null hypothesis that the population parameter p is equal to 0.66 against the alternative hypothesis that p is greater than 0.66. Complete parts a through c below. E) a. Noting that B: 0.72, does the value ofp appear to contradict the null hypothesis? The value 0pr appears to contradict the null hypothesis because it satises the alternative hypothesis and is not very close to 0.66. b. Use the largesample ztest to test H0: p = 0.66 against the alternative hypothesis Ha: p > 0.66. Use or = 0.05. The test statistic is D. (Round to two decimal places as needed.)
