A researcher wants to know whether athletic men are more flexible than nonathletic men. For this experiment, a man who exercised vigorously at least four times per week was considered "athletic." Flexibility is measured in inches on a sit & reach-box. Test the researcher's claim using the following summary statistics (use 5% level of significance): Athletic Men n = 50 * = 4.3 inches s = 2.1 inches Nonathletic Men h= 40 x = 3.2 inches s = 1.0 inches Assume that all conditions for testing have been met. Be sure to report the null and alternative hypotheses, test statistic, p-value, your decision regarding the null hypothesis, and your conclusion about the original claim. Round all values to the nearest thousandth. (a) Provide detailed calculations; use technology to calculate required percentiles. (b) Verify your results using technology (provide the output).

Transcribed Image Text:A researcher wants to know whether athletic men are more flexible than nonathletic men. For this
experiment, a man who exercised vigorously at least four times per week was considered "athletic." Flexibility
is measured in inches on a sit & reach-box. Test the researcher's claim using the following summary statistics
(use 5% level of significance):
Nonathletic Men
h = 40
x = 3.2 inches
s = 1.0 inches
Athletic Men
n = 50
x = 4.3 inches
s = 2.1 inches
Assume that all conditions for testing have been met. Be sure to report the null and alternative hypotheses,
test statistic, p-value, your decision regarding the null hypothesis, and your conclusion about the original
claim. Round all values to the nearest thousandth.
(a) Provide detailed calculations; use technology to calculate required percentiles.
(b) Verify your results using technology (provide the output).
