Use the following information to answer the next two questions:
A researcher conducted a one-sample t-test which compared the average heart rate in the general population (µ = 85) to a sample of 25 professional athletes (= 82, S =1.5), and rejected the null hypothesis that there was no difference in heart rate for the two populations.
_____16. What is the correct tcritical value to use in computing the 95% confidence interval using the data above?
a. 1.77
b. 2.064
c. 2.492
d. 2.797
_____ 17. After computing the confidence interval, the researcher found values of 81.5 and 82.5. What is the correct interpretation for the confidence interval?
P(81.5 < μathlete> 82.5) = .95
a. We are 95% sure that the general population has a mean heart rate between 81.5 and 82.5
b. We are 95% sure that the population of athletes has a mean heart rate between 81.5 and 82.5
c. We are 95% confident that athletes have the same heart rate as the general population.
d. None of the above
