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.

We should not reject the null hypothesis because t0>tα. 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 193days.

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.
