Question

You want to know whether high-school females are more likely to pass an AP Calculus class than high-school males. You take a random sample of males and females from high-school AP Calculus courses across the country and record whether each receives a passing or failing grade. Which confidence interval would you use to analyze the data? p cap plusminus z* s/squareroot n x bar_1 - x bar_2 plusminus t* squareroot s^2_1/n_1 + s^2_2/n_2 x bar_1 - x bar_2 plusminus t* S_p squareroot 1/n_1 + 1/n_2 x bar plusminus z* sigma/squareroot n p^cap_1 - p^cap_2 plusminus z* squareroot p^cap_1(1 - p^cap_1)/n_1 + p^cap_2(1 - p^cap_2)/n_2

Explanation / Answer

Here two proportions are to be compared. Thus confidence interval given in E is to be used.
