Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
You recently sent out a survey to determine if the percentage of adults who use social media has changed from 58%, which was the percentage of adults who used social media five years ago.

A statistics content developer at Aplia wanted to know whether study skills are related to memory quality. She invited student volunteers to perform an online memory task. The students saw a list of 60 words and were then asked to recognize a list of 10 words that were on the original list. Students were also asked to provide their GPAs. Consider the following data set, which was collected from student volunteers in 2009. The table gives the frequency for five intervals of scores on the number of correctly identified words. Use the dropdown menus to complete the table by filling in the missing values for the proportions and percentages. Score Interval f Proportion Percentage 9–10 29 0.19 19% 7–8 53 5–6 50 3–4 22 0.14 14% 1–2 1 0.01 1%
Many high school students take the AP tests in different subject areas. In one year, of the 144,651 students who took the biology exam 84,698 of them were female. In that same year, of the 214,919 students who took the calculus AB exam 125,498 of them were female. Estimate the difference in the proportion of female students taking the biology exam and female students taking the calculus AB exam using a 99% confidence level. Round to four decimal places. With 99 O % confidence, it can be concluded that the true difference in the proportion of female students taking the biology exam and the proportion of female students taking the calculus AB exam (P₁ - P2) is between and
