Question
Suppose a Tim Horton's Manager wants the standard deviation of wait times at the drive through to
be less than 4 minutes. A recent sample of 25 customers reveals a sample standard deviation wait
time of 3.5 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)
