You wish to test the following claim (Ha) at a significance level of α=0.005. Ho:p=0.27 Ha:p>0.27 You obtain a sample of size n=587 in which there are 168 successful observations. For this test, you should use the (cumulative) binomial distribution to obtain an exact p-value. (Do not use the normal distribution as an approximation for the binomial distribution.) The p-value for this test is (assuming Ho is true) the probability of observing... a) at most 168 successful observations b) at...
