A research team wishes to test whether there is a statistically significant difference in systolic blood pressures between two populations. The systolic blood pressures were measured for two samples taken independently from the two populations, and are listed below. If the Wilcoxon Rank Sum test is used for this problem, which of the followings is(are) correct?

Group A 144 152 155 149 151 148
Group B 143 152 148 145 144 147

a. The asymptotic test p-value is .063
b. The asymptotic test p-value is .126.

c. Wilcoxon Rank Sum Test can not be used for this case.

d. The asymptotic test p-value is .041.

    A team of researchers is investigating a drug for reducing systolic blood pressure. Two groups each has 6 subjects were selected in this study. Group A is the control group. The treatment was used for group B. A fixed increased amount of doses were used on group C. The systolic blood pressures were measured for all groups and are listed below. This team wishes to test whether there is a statistically significant difference in average systolic blood pressures between the...

    please help desperately need it 7) When subjects were treated with a drug, their systolic blood pressure readings (in mm Hg) were measured before and after the drug was taken. Results are given in the table below. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Using a 0.05 significance level, is there sufficient evidence to support the claim that the drug is effective in lowering systolic...

    Suppose you are testing whether there is a statistically significant difference in systolic blood pressure (mmHg) between a treatment and placebo group; that is, positive values indicate the treatment is more effective than the placebo, and negative values indicate the placebo is more effective than the treatment. The 95% CI is [8, 17] . Based on this interval, did the treatment group outperform the placebo, or vise versa? Should you reject or fail to reject the null hypothesis of no...

Also, write a directional hypothesis that reflects the anticipated outcome. Conduct a t-test two-sample assuming unequal variances using Excel. Interpret the Excel result (was it significant, what was the critical t-value, what was the calculated t-value, what should be done with the null hypothesis—accept or reject)....
