Identify the null hypothesis,alternative hypothesis,test statistic,p-value,conclusion about the null hypothesi?

I believe the question is a difference in one bi proportion. the null is Ho: p=.5 and the alternative is H1: p>.5. Choose sig level of .01. Cr region is Reject null if z>z.05=1.645. test stat: Zcalc=x-n*Po/sq root of n*Po*Qo. Po=45% and Qo=55% osl or p value is Ho: p=.5 H1:p>.5 This should be enough info to solve
