Transcribed Image Text:The accompanying table shows the technology output for a test using data on the pulse rates of several hundred people to see whether men or women tended to have higher pulse rates. The data are random and independent.
Complete parts (a) and (b) below.
Click the icon to view the technology output.
a. Report the sample means, and state which group had the higher sample mean pulse rate.
The women's sample mean pulse rate of
v the men's sample mean pulse rate of
was
(Type integers or decimals. Do not round.)
b. Use the technology output to test the hypothesis that the pulse rates for men and women are not equal, using a significance level of 0.05. The samples are large enough so that Normality is not an issue.
Determine the hypotheses for this test. Let u be the population mean pulse rate. Choose the correct answer below.
O A. Hg: Hwomen * Hmen
Ha: Hwomen = Hmen
O B. Ho: Hwomen <Hmen
Ha: Hwomen = Hmen
OC. Ho: Hwomen = Pmen
Ha: Hwomen <Hmen
O D. Ho: Hwomen = Hmen
Ha: Hwomen > Hmen
O E. Ho: Hwomen = Hmen
H3: Hwomen * Hmen
O F. Ho: Hwomen> Hmen
H3: Hwomen = Hmen
Find the test statistic for this test.
t=(Type an integer or a decimal. Do not round.)
Find the p-value for this test.
p-value =(Type an integer or a decimal. Do not round.)

What is the conclusion for this test?
O A. Do not reject H. At the 5% significance level, there is insufficient evidence to conclude that the mean pulse rate of men is different from the mean pulse rate of women.
O B. Reject H,. At the 5% significance level, there is insufficient evidence to conclude that the mean pulse rate of men is different from the mean pulse rate of women.
O C. Reject Hn. At the 5% significance level, there is sufficient evidence to conclude that the mean pulse rate of men is different from the mean pulse rate of women.
O D. Do not reject H,. At the 5% significance level, there is sufficient evidence to conclude that the mean pulse rate of men is different from the mean pulse rate of women.
