You wish to test the following claim (Ha) at a significance level of a = 0.005. Ho: p = 0.78 Ha: p > 0.78 You obtain a sample of size n = 621 in which there are 508 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 H, is true) the probability of observing... O at most 508 successful observations at least 508 successful observations What is the p-value for this sample? (Report answer accurate to four decimal places.) p-value = The p-value is... less than (or equal to) a greater than a This test statistic leads to a decision to... O reject the null O accept the null fail to reject the null
