The mean throwing distance of a football for Marco, a high school freshman quarterback, is 40.4 yards, with a standard deviation of 1.9 yards. The team coach tells Marco to adjust his grip. The coach records the distances for 24 throws. For the 24 throws, Marco's mean distance was 41.3 yards. The coach thought the different grip made Marco throw more than 40.4 yards. Conduct a hypothesis test using an alpha level of 0.05. Assume the throw distances for footballs are normally distributed. Round answers to 4 decimals where possible. 1.

Transcribed Image Text:The mean throwing distance of a football for Marco, a high school freshman quarterback, is 40.4 yards,
with a standard deviation of 1.9 yards. The team coach tells Marco to adjust his grip. The coach
records the distances for 24 throws. For the 24 throws, Marco's mean distance was 41.3 yards.
The coach thought the different grip made Marco throw more than 40.4 yards. Conduct a hypothesis
test using an alpha level of 0.05. Assume the throw distances for footballs are normally distributed.
Round answers to 4 decimals where possible.
