Question

i need help with #13 please explain in detail

11. State the interval. The interval is (0.506041,0.852655) 12. Interpret the interval. We are 95% confident that the population mean of the females that exercise regularly are between 0.506041 and 0.852655. Descriptive Statistics N Event Sample p95% CI for p 30 21 0.700000 (0.506041, 0.852655) 13. Suppose that you are a journalist that has been asked to summarize the results of this study. Give a brief summary of the results so that a friend who is not taking a statistics course would understand it. Hint: What did the confidence intervals reveal? Give an interpretation of the intervals, but breakdown the terms population mean, population proportion and confidence.

Answer 1

Hi,

We have given that:

Confidence interval=(0.506041,0.852655)

This means we are 90%confident that population mean of populations proportion of female that exercise regularly is between 0.506041 and 0.852655.

Extra→Population mean interval of female who exercise regular=(Np',Np)=(30*0.506041,30*0.852655)=(15.181,25.5796)

Thanks!
