Suppose a Tim Horton's Manager wants the standard deviation of wait times at the drive through to be at most 5 minutes. A recent sample of 35 customers reveals a sample standard deviation wait time of 6.5 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) Determine the appropriate critical value (round to 3 decimal places as needed) 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 insufficient evidence to reject the Manager's claim. O Do not reject the null hypothesis. There is sufficient evidence to reject the Manager's claim. O Reject the null hypothesis. There is sufficient evidence to support 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. Do not reiect the null hypothesis. There is insufficient evidence to reiect the Manager's claim.
