he mean throwing distance of a football for a Luis, a high school freshman quarterback, is 50 yards, with a standard deviation of three yards. The team coach tells Luis to adjust his grip to get more distance. The coach records the distances for 35 throws. For the 35 throws, Luis's mean distance was 54 yards. The coach thought the different grip helped Luis throw farther than 50 yards. Conduct a hypothesis test using a preset α = 0.01. Assume the throw distances for footballs are normal.

a.       Determine what type of test this is: A, B or C?

Blank 1

A) Single population mean with standard deviation known

B)  with standard deviation not known

C) Single population p

b.      Identify the null hypothesis, A, B,C or D?

Blank 2

C) 

c.       Find the test-statistic to 2 decimal places

Blank 4

d.      Find the p-value to nearest whole number

Blank 5

e.      State your conclusion, A, B, or C?

Blank 6

 A.   There is not sufficient evidence from this sample data to show that Luis's mean throwing distance is greater than 50 yards.

 B.  R There is sufficient evidence from this sample data to show that Luis's mean throwing distance is greater than 50 yards.

 C. no conclusion
