Two random samples are taken, one from among first-year UVA students and the other from among fourth-year UVA students. Both samples are asked if they favor modifying the Honor Code. A summary of the sample sizes and number of each group answering yes'' are given below:

First-Years (Pop. 1)::n1=84,x1=45

Fourth-Years (Pop. 2)n2=90 x2=45

Is there evidence, at a=0.07 level of significance, to conclude that there is a difference in proportions between first-years and fourth-years? Carry out an appropriate hypothesis test, filling in the information requested.

A. The value of the standardized test statistic: ?

B. The p-value is ?
