Question 1178194: In a simple random sample of size 50, there were 17 individuals that answered yes to the category of interest. It is desired to test Ho:p more than or equal to 0.36 versus Ha: p is less than 0.36. Do you reject Ho at the 0.05 significance level?
a. No because the z score is larger than zc
b. Yes because the z score is larger than zc
c. No because the z score is smaller than zc
d. Yes because the z score is smaller than zc

Hi

Ho:  p = .36

Ha:  p < .36

sample:  n = 50 mean = 17/50 =  .34

σ = 0.05, 0r  .95 (z = 1.96) 

 z+=blue+%28-.02%29%2Fsqrt%28blue%28.36%28.64%29%2F50%29%29 = -.2946

|-.2964| < 1.96

Do you reject Ho?

a. No because the |z-score| is smaller than zc
