The following data were collected from a random sample of 12 NFLgames. (See exercise 49 on page 37 of your textbook for a similar problem.) Minutes standing around between plays 69.49 68.18 63.13 74.01 67.91 65.32 59.47 66.66 69.97 64.13 73.09 60.66 HWNotes HWExcelDirections HW Texting Unemployed ADY O Type here to search
Question 3 A Test the hypothesis that the average time NFL players spend standing around between plays during a game is 61.68 minutes at α=0.02.
Step 1:
H0: µ
Ha: µ
Step 2: =
Step 3: Fill in the row if the hypothesis is one-tailed.
Reject H0 if
Fill in the row if the hypothesis is two tailed. The smaller number must be typed first.
Reject H0 if or
Step 4: =
Step 5: H0
Step 6:
Step 7: Fill in the row if the Z table is appropriate.
P-value =
Fill in the row if the t table is appropriate. The lower boundary must go on the left and the upper boundary on the right.
P-value
Question 3 B Construct a 80% confidence interval for the population average time NFL players spend standing around between plays during a game.
Lower Endpoint Upper Endpoint
Question 3 C What would the P-value be if this were a lower tail hypothesis test? (Mathematically manipulate the P-value from part A to get your answer.)
Fill in the row if the Z table is appropriate.
P-value =
Fill in the row if the t table is appropriate. The lower boundary must go on the left and the upper boundary on the right.
(Lower Boundary) P-value (Upper Boundary)
