The accompanying data are drive-through service times (seconds) recorded at a fast food restaurant during dinner times. Assuming that dinner service times at therestaurant's competitor have standard deviation σ=58.8 sec, use a 0.025 significance level to test the claim that service times at the restaurant have the same variation as service times at its competitor's restaurant.

The accompanying data are drive-through service times
(seconds) recorded at a fast-food restaurant during dinner times.
Assuming that dinner service times at the restaurant's competitor
have standard deviation σ = 61.4sec, use a 0.01 significance level
to test the claim that service times at the restaurant have the
same variation as service times at its competitor's restaurant.
Use the accompanying data to identify the null hypothesis,
alternative hypothesis, test statistic, and P-value. Then state
a conclusion about the null hypothesis....
