2. A researcher is testing the hypothesis that consuming a sports drink during exercise will improve endurance. A sample of n = 50 male college students is obtained and each student is given a series of three endurance tasks and asked to consume 4 ounces of the drink during each break between tasks. The overall endurance score for the sample is M = 53. For the general population, without any sport drink, the scores for this task average u = 50 with a standard deviation of o = 12. Can the researcher conclude that endurance scores with the sports drink are significantly higher than scores without the drink? Use a one-tailed one sample z-test with a = .05.

Transcribed Image Text:2. A researcher is testing the hypothesis that consuming
a sports drink during exercise will improve
endurance. A sample of n = 50 male college students is
obtained and each student is given a series of three
endurance tasks and asked to consume 4 ounces of the
drink during each break between tasks. The overall
endurance score for the sample is M = 53. For the
general population, without any sport drink, the
scores for this task average µ = 50 with a standard
deviation of o = 12.
Can the researcher conclude that endurance scores
with the sports drink are significantly higher than
scores without the drink? Use a one-tailed one sample
z-test with a = .05.
3. Refer back to problem #2. This time use a two-tailed
one sample z-test with a = .05. Can the researcher now
conclude that endurance scores with sports drinks are
significantly different than scores without the drink?
