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. What are the null and alternative hypotheses that this team should use? a. H0:μ=133, Ha:μ<133. b. H0:μ=133, Ha:μ>133. c. H0:μ=133, Ha:μ ≠=133.
