Using the picture below, solve parts I-IIIII) state the null hypothesis and alternative hypothesis which is correct?a. H0:u1=u2; Ha: u1#u2b. H0:u1=u2; ha:u1u2II) identify the p value III) state the researchers conclusion which is correcta. Fail to reject H0, there is not sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of womenb. Fail to reject H0, there is sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of womenC. Reject H0, there is not sufficient evidence to conclude that the mean step pulse of men was less than the mean step pulse of womend. Reject H0, there is sufficient evidence-to conclude that the mean step pulse of men was less than the mean step pulse of womenIIII) what is the 90% confidence interval for the mean difference in pulse rates of men versus women? The lower bound is ___The upper bound is ___(Round to two decimal places)Interpret the result a. We are 90% confident that the mean difference is the confidence interval b. 90% of the time the mean difference is the confidence intervalc. We are 90% confident that the means are in the confidence interval d. 90% of the time the means are in the confidence interval

A physical therapist wanted to know whether the mean step pulse of men was less than the Two sample T for Men vs Women mean step pulse of women. She randomly selected 50 men and 75 women to participate in N Mean StDev SE Mean the study. Each subject was required to step up and down a 6-inch platform. The pulse of Men 50 112.2 11.4 16 each subject was then recorded. The following results were obtained Women 75 118.4 14 4 1.7 90% CI for mu Men - mu Women (a) State the null and alternative hypotheses. Which of the following is correct? O A. Ho H1 = H2 Ha H1 * H2 O B. Ho: 1 = 15. H2 : 1
