What would be the null and alternative hypotheses

Reference no: EM132501726

We would like to test if the proportion of Tulane undergraduate students who are studying for their doctorate is 0.25. Suppose we take a sample of 30 Tulane graduate students.

a) What would be the null and alternative hypotheses?

b) What is the mean of the sample proportion, , who are studying for their doctorate degree, in samples of size 30.

c) What is the standard deviation of the sample proportion, , who are studying for their doctorate degree, in samples of size 30.

d) What would be the sample proportion if 9 of the 30 Tulane undergraduate students were studying for their doctorate?

e) Find the z-score of the sample proportion, if, in a sample of 30 Tulane undergraduate students 9 are studying for their doctorate.

f) Is the z-statistic large?

g) Can we reject the Null hypothesis?

h) Is there evidence that the proportion of Tulane undergraduate students who are studying for their doctorate is 0.25?
