A recent report states the variance of the fuel consumption of a certain car is equal to 16.81 miles per gallon (mpg). A researcher claims the actual variance is lower. A sample of 21 cars produced a variance of 6.25 mpg. Test the claim at alpha = 0.05, use the P-value method. For question #29, tell what type of test his is (right, left, or two-tailed). For question #30, select from choices given with regard to identifying the alternate hypothesis. For question #31, fill in the blank with your Critical Value(s) for Chi-square.

For question #29, tell what type of test his is (right, left, or two-tailed).
For question #30, select from choices given with regard to identifying the alternate hypothesis.
For question #31, fill in the blank with your Critical Value(s) for Chi-square.
For question #32, fill in the space provided with your calculated value of Chi-square.
For question #33, use your answer from #32 to select between which two areas your P-value lies.
For question #34, based on your answer for #33, answer True or False as to whether the null hypothesis will be rejected.
