B) the standard error of x1 - x2 is

C)what is the 95% confidence interval for the difference between the two means?

D) what is the test statistic for the difference between the two population means?

E) what is the p-value for the difference between the two population means?

F) what is the conclusion that can be made about the difference between the two population means? (use a .05 level of significance)

In order to determine whether there was a difference in the survival rate between females and males, a two-sample proportion test was applied. The following is the output for the test with some entries missing: Two sample proportion hypothesis test: p1 : Proportion of successes (Success = Survived) for Survival where Gender=Female p2 : Proportion of successes (Success = Survived) for Survival where Gender=Male p1 - p2 : Difference in proportions H0 : p1 - p2 = 0 HA :...

1. A study was conducted to determine whether there were significant difference between medical students admitted through special programs (such as affirmative action) and medical students admitted through the regular admissions criteria. It was found that the graduation rate was 94% for the medical students admitted through special programs (based on data from the Journal of the American Medical Association). (a) If 10 of the students from the special programs are randomly selected, find the probability that at least 9...
