Use the following information for Questions 19-21. Teresa works at a medium-sized doctor's office and notices that appointment times are approximately normally distributed with mean 25 minutes and standard deviation 10 minutes. A patient complains that the wait times are too long and that her average wait time is much longer than 25 minutes. Teresa decides to conduct a test with a = 0.05 and the following hypotheses Ho: H=25 vs. Ha:μ> 25 Teresa randomly selects 25 appointments and records their times and finds their mean. The P-value of the test of the null hypothesis is O the probability the null hypothesis is false. O the probability, assuming the null hypothesis is true, that the test statistic will take a value at least as extreme as that actually observed. O the probability, assuming the null hypothesis is false, that the test statistic will take a value at least as extreme as that actually observed. O the probability the null hypothesis is true.
