You wish to test the following claim (Ha) at a significance level of a = 0.001.Ho: p= 0.28Ha: p > 0.28You obtain a sample of size n = 351 in which there are 126 successful observations. For this test, youshould use the (cumulative) binomial distribution to obtain an exact p-value. (Do not use the normaldistribution as an approximation for the binomial distribution.)
