a. Test if there is significant difference between the mean of the enrollments at α = 0.05.
b. Find the 95% confidence interval for the difference in the means.

Respuesta :

There is a significant difference between the mean of the enrollments at α = 0.05 in the hypothesis.

How to illustrate the information?

p-value = 0.0749

p.value >0.0.5

We Accept H0 at 0.05 significance level

Therefore, the mean enrollments for the two groups are not the same

p-value at (z = 1.918) for right-tailed test is 0.0276 or 2.76% (Using excel formula 1-NORM.S.DIST(1.918, TRUE))

As p-value is less than 5% significance level, we reject the null hypothesis.

Therefore, we have sufficient evidence to support the claim that more medical students enroll in research-oriented medical schools (p-value = 2.76%).

The 95% confidence interval is (-11.5746, 228.5452)
