A doctor's office believes the number of flu cases is decreasing. The doctor's office would like to test the claim that the average number of flu cases per day at the doctor's office is under 6 cases. Using the computed test statistic of −1.90 and the critical value of −1.28, is there enough evidence for the doctor's office to reject the null hypothesis? Use the graph below to interpret the critical value. First select the appropriate test type (left-, right-, or two-tailed), then plot the points along the x-axis (for the critical value and test statistic), and use them to choose the appropriate interpretation. powered by $$z=−0.62 Rejection region Move the blue dot to choose the appropriate test Test Statistic 1.24 Select the correct answer below: Yes. There is sufficient evidence for the doctor's office to reject the null hypothesis because the critical valuefalls in the rejection region. No. There is NOT sufficient evidence for the doctor's office to reject the null hypothesis because the critical value does not fall in the rejection region. Yes. There is sufficient evidence for the doctor's office to reject the null hypothesis because the test statistic falls in the rejection region. No. There is NOT sufficient evidence for the doctor's office to reject the null hypothesis because the test statisticdoes not fall in the rejection region.
