If m1 = Driver Chest Injury Rating and m2 = Passenger Chest Injury rating,
Is this the correct null and alternate hypothesis based on the following question?
Formulate the appropriate null and alternative hypotheses (in both sentence and numerical form) to determine whether the true mean driver chest injury rating exceeds the true mean passenger chest injury rating
Ho: m1 > m2
Ha: m1 < m2
Null hypothesis: The mean of the Drivers Chest Injury is greater than the mean of the Passenger Chest Injury.
Alternate Hypothesis: The mean of the Drivers Chest Injury is less than the mean of the Passenger Chest Injury.
