Question 980123
This is a one sample proportion test.
Ho p>=0.45
Ha p<0.45
alpha=0.05
Test statistic (phat-p) *se;  se=sqrt {(0.45)(0.55)/50}=0.0704
Critical value at the 0.05 level is z=-1.645
Test stat=(0.36-0.45)/0.0704 =-1.278
p=0.1006
Fail to reject the null hypothesis at the 0.05 level.
The best that could be done is p<0.11, although it is very close to p=0.10
