21 As a part of her studies, Gail gathered data on the speeds of testing procedure: vehicles traveling on a highway. She works through the α 0.05 The test statistic is to 0.643 The critical value is too5 1.725. At the 5% significance level, does the data provide sufficient evidence to conclude that the mean speed of vehicles traveling on the highway is more than 61 miles per hour? Select the correct answer below: O We should reject the null hypothesis because to < ta. So, at the 5% significance level, the data provide sufficient evidence to conclude that the average speed of vehicles traveling on the highway is greater than 61 miles per hour. O We should not reject the null hypothesis because o < a. So, at the 5% significance level, the data do not provide sufficient evidence to conclude that the average speed of vehicles traveling on the highway is greater than 61 miles per hour. O We should reject the null hypothesis because to > ta. So, at the 5% significance level, the data provide sufficient evidence to conclude that the average speed of vehicles traveling on the highway is greater than 61 miles per hour.
