Question
a) Drop down options:
equal to higher than lower than 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 ofwas (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 the men's sample mean pulse rate of enough so that Normality is not an issue Determine the hypotheses for this test. Let be the population mean pulse rate. Choose the correct answer below HaHwomen .men Find the test statistic for this test. | | (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? 0 A, O B. ° C. 0 D. Reject Ho. 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 Do not reject Ho. 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 Do not reject H0. 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 Reject Ho. 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 womenExplanation / Answer
The sample means are
Female = 75.2
Male = 71.5
hence women pulse rate is higher then men pulse rate
as we want to test the difference , hence the claim is that mu female is not equal to mu men
hence correct choice is E
The t stat from the output is 3.83
p value frm the output table is 0.000
as the p value is less than 0.05 ,hence we reject null hypothesis in favor of alternate hypothesis to conclude that the means values are different for mean and women
Hence A
