Question 1079347
The point estimate is 0.5205
the se=sqrt (0.5*0.5/1026)=0.0156
the 95% CI is an interval 0.0156*1.96=0.0306
The CI is (0.4900, 0.5511)
Since 0.5 is in the confidence interval, there is insufficient evidence to reject Ho.
All the other parts of the hypothesis test can be filled in.  The test is a one sample proportion, and reject for |z|>1.96, z's being the test statistic.
I did CI, but z=1.31 if it is done that way, and one still doesn't reject.
