Suppose a Tim Horton's Manager claims the standard deviation of wait times at their drive through is 3 minutes. A recent sample of 28 customers reveals a sample standard deviation wait time of 3.75 minutes. Test whether or not the Manger's goal was achieved using a 5% level of significance. Calculate the appropriate test statistic (round to 2 decimal places as needed) Enter each critical value (round to 3 decimal places as needed) enter the smaller critical value here: enter the larger critical value here: Determine the appropriate p-value (round to 3 decimal places as needed) Which of the following is your conclusion based on the information above: O Reject the null hypothesis. There is sufficient evidence to support the Manager's claim. O Do not reject the null hypothesis. There is insufficient evidence to reject the Manager's claim. O Reject the null hypothesis. There is sufficient evidence to reject the Manager's claim. O Do not reject the null hypothesis. There is insufficient evidence to support the Manager's claim. O Reject the null hypothesis. There is insufficient evidence to reject the Manager's claim. O Do not reiect the null hvpothesis There is sufficient evidence to reiect the Manager's claim.

Transcribed Image Text:Suppose a Tim Horton's Manager claims the standard deviation of wait times at their drive through
is 3 minutes. A recent sample of 28 customers reveals a sample standard deviation wait time of 3.75
minutes. Test whether or not the Manger's goal was achieved using a 5% level of significance.
Calculate the appropriate test statistic (round to 2 decimal places as needed)
Enter each critical value (round to 3 decimal places as needed)
enter the smaller critical value here:
enter the larger critical value here:
Determine the appropriate p-value (round to 3 decimal places as needed)
Which of the following is your conclusion based on the information above:
O Reject the null hypothesis. There is sufficient evidence to support the Manager's claim.
O Do not reject the null hypothesis. There is insufficient evidence to reject the Manager's claim.
O Reject the null hypothesis. There is sufficient evidence to reject the Manager's claim.
O Do not reject the null hypothesis. There is insufficient evidence to support the Manager's
claim.
O Reject the null hypothesis. There is insufficient evidence to reject the Manager's claim.
O Do not reiect the null hvpothesis There is sufficient evidence to reiect the Manager's claim.
