A university wants to start a hockey team finding that 83%of a random sample of 100 people support the establishment of said team. However, the sample appears to contain 80 men and 20 women; another random sample of the university body suggests that the true percentage of support for a hockey team is 55%. Calculate the test statistic one would use to determine if there is a significant difference between the male dominated sample and the "normal" sample

(I got 5.63, but apparently that wasn't correct so I am stumped on solving this problem).
