Many high school students take the AP tests in different subject areas. In one year, of the 144,140 studentswho took the biology exam 84,545 of them were female. In that same year, of the 216,298 students whotook the calculus AB exam 126,501 of them were female. Estimate the difference in the proportion offemale students taking the biology exam and female students taking the calculus AB exam using a 99%confidence level. Round to four decimal places.With% confidence, it can be concluded that the true difference in the proportion offemale students taking the biology exam and the proportion of female students taking the calculus AB exam(P1-P2) is betweenand

In politics, marketing, etc. we often want to estimate a percentage or proportion p. One calculation in statistical polling is the margin of error - the largest (reasonble) error that the poll could have. For example, a poll result of 72% with a margin of error of 4% indicates that p is most likely to be between 68% and 76% (72% minus 4% to 72% plus 4%). In a (made-up) poll, the proportion of people who like dark chocolate more than milk chocolate was 37% with a margin of error of 2.5%. Describe the conclusion about p using an absolute value inequality. . That lets you type in a vertical bar | to represent absolute values. Also, when you type in < and then =, the symbolic entry option will automatically convert that to ≤ . In the same way, if you type in > and then =, the symbolic entry option will automatically convert that to ≥. Be sure to use decimal numbers in your answer (such as using 0.40 for 40%).

A survey conducted by a song rating service finds that the percentages of listeners familiar with "Poker Face" by Lady Gaga who would give the song ratings of 5, 4, 3, 2, and 1 are, respectively, 43 percent, 21 percent, 22 percent, 7 percent, and 7 percent. Assign the numerical values 1, 2, 3, 4, and 5 to the (qualitative) ratings 1, 2, 3, 4, and 5 and find an estimate of the probability distribution of x = this song’s rating by a randomly selected listener who is familiar with the song. Find the expected value of the estimated probability distribution. (Round your answer to 2 decimal places.)
Construct the 99% confidence interval for the difference when ,-476.88, x-318.32, , -42.11, -26.80, -19, and #₂ -22. Use the TI-84 Plus calculator and round the answers to two decimal places. A 99% confidence interval for the difference in the population means is
A researcher wanted to estimate the proportion of undergraduate college students (18– 29 years) with access, so she randomly sampled 195 undergraduates and found that 175 had access. Estimate the true proportion with 95% confidence. Round intermediate answers to five decimal places. Round your final answer to one decimal place.
A recent survey conducted in a nearby town showed that 791 out of 1,495 people do most of their holiday shopping online. Find the lower bound of the 90% confidence interval for the true proportion of people that do most of their holiday shopping online. Write your answer to three decimal places.
