Question

The average wait time to get seated at a popular restaurant in the city on a Friday night is 9 minutes.  Is the mean wait time greater for men who wear a tie? Wait times for 11 randomly selected men who were wearing a tie are shown below. Assume that the distribution of the population is normal.

10, 10, 10, 10, 11, 7, 8, 7, 11, 9, 8

What can be concluded at the the αα = 0.05 level of significance level of significance?

  1. For this study, we should use    
  2. The null and alternative hypotheses would be:     

 H0:H0:                 

 H1:H1:              

  1. The test statistic     =  (please show your answer to 3 decimal places.)
  2. The p-value =  (Please show your answer to 4 decimal places.)
  3. The p-value is     αα
  4. Based on this, we should      the null hypothesis.
  5. Thus, the final conclusion is that ...
    • The data suggest the population mean is not significantly more than 9 at αα = 0.05, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is equal to 9.
    • The data suggest that the population mean wait time for men who wear a tie is not significantly more than 9 at αα = 0.05, so there is statistically insignificant evidence to conclude that the population mean wait time for men who wear a tie is more than 9.
    • The data suggest the populaton mean is significantly more than 9 at αα = 0.05, so there is statistically significant evidence to conclude that the population mean wait time for men who wear a tie is more than 9.
