As a part of her studies, Jamie gathered data on the length of time between dentist visits for a sample of 20 individuals. She works through the testing procedure: 0 : μ 193; Ha : μ < 193 . The test statistic is x_Ho 0.455 · The critical value is-t0.1- 1.328 At the 10% significance level, does the data provide sufficient evidence to conclude that the mean length of time between dentist visits is less than 193 days? Select the correct answer below: O We should reject the null hypothesis because to 4. So, at the 10% significance level, the data provide sufficient evidence to conclude that the average length of time between dentist visits is less than 193 days. O We should not reject the null hypothesis because ț0 〈α. So, at the 10% significance level, the data do not provide sufficient evidence to conclude that the average length of time between dentist visits is less than 193 days O We should reject the null hypothesis because to 4. So, at the 10% significance level, the data provide sufficient evidence to conclude that the average length of time between dentist visits is less than 193 days.
