Answer #1

Correct option:

A     We use the confidence interval. It is centered at 0.17

Explanation:

\hat{p}f = Proportion of females = 176/320 = 0.55

\hat{p}m = Proportion of males = 114/300 = 0.38

So,

pf - pm = 0.55 – 0.38 = 0.17

    This question is based on Ch10, but we can solve it using our knowledge from Ch9. In Ch 8, we created confidence intervals to test whether the means differed in a statistically significant manner between two independent (unrelated) populations, like males and females. The sample point estimator in the confidence interval was the difference in the sample means between the 2 samples (xbar - ybar). We created a confidence interval of the form: (xbar-ybar) +/- (Zα/2)[standard error of (xbar-ybar)] We...
