Aprivate and a public university are located in the same city. for the private university, 1038 alumni were surveyed and 647 said that they attended at least one class reunion. for the public university, 808 out of 1311 sampled alumni claimed they have attended at least one class reunion. is the difference in the sample proportions statistically significant? (use α=0.0

The difference in the sample proportions is not statistically significant at 0.05 significance level.

Step-by-step explanation:

Significance level is missing, it is  α=0.05

Let p(public) be the proportion of alumni of the public university who attended at least one class reunion  

p(private) be the proportion of alumni of the private university who attended at least one class reunion  

Hypotheses are:

: p(public) = p(private)

: p(public) ≠ p(private)

The formula for the test statistic is given as:

z= where

Then z= =-0.207

Since p-value of the test statistic is 0.836>0.05 we fail to reject the null hypothesis.
