Question 1080923: We gather a sample of 50 people from a gym and find the sample proportion is 0.6 women.
a.What is percent of women in the population? =Unknown/not given
b.Why does X ̅(bar) vary randomly?
c.Construct a 95% C.I.?
d.Is it plausible that µ is 55 percent? Yes
Was the Success-Failure Conditioned satisfied?
Was the 10% condition satisfied?
You can put this solution on YOUR website! Point estimate is 60%
It varies because different samples cannot be expected to have identical results.
95% CI has interval of 1.96*SE=1.96 +/- sqrt (.6*.4/50)=0.1358
The 95% CI is approximately (0.465, 0.735)
It is entirely plausible mu is 55%
The conditions are satisfied.
