Question 387906
1) 


You should have gotten (0.48, 0.53) as your 96% CI, what did you get for z and p?


2) 


Your null hypothesis is correct, but your alternative hypothesis should be 


{{{H[a]}}}: {{{p<>0.44}}}


3) 


I'm not understanding the question. Are you comparing these two means? Or is one mean a sample mean and the other a population mean? I'm sure there's more to this problem.


If you're doing a significance test, then your p-value is actually much larger.
