A professional racing team is holding tryouts at its test track. The team requires its drivers to have an average lap time of at most 133 seconds at its test track. The team will use a one sample z-test of significance to determine if they should hire a new driver. Using the P-value you computed in the previous problem, determine if the team has significant evidence (at level 0.05) that this driver should not join the team. a. Yes, the data is significant at level 0.05, so we reject H0, which assumed the driver had the needed average lap time. b. No, the data is significant at level 0.05, so we fail to reject H0, which assumed the driver had the needed average lap time. c. No, the data is not significant at level 0.05, so we fail to reject H0, which assumed the driver had the needed average lap time. d. Yes, the data is significant at level 0.05, so reject Ha.
