# Problem 2Case studies suggested that out of 12,575 convicts who escaped from US prisons, only 7,262 were recaptured. ### A. Calculating the Point Estimate- **Objective:** Find the point estimate for the population proportion from these studies.- **Instructions:** Show your simplified fraction for the point estimate and use proper notation.### B. Constructing a 95% Confidence Interval- **Objective:** Build a 95% confidence interval for the real population proportion by hand using the formula.- **Instructions:** Show every step. Draw a picture that represents the problem and clearly indicate your final answer.### C. Interpretation- **Objective:** Use a complete sentence or two to interpret your confidence interval.

You want to estimate the percentage of adults who believe that passwords should be replaced with biometric security (such as fingerprints). How many randomly selected adults must you survey? Assume that you want to be 90% confident that the sample percentage is within 4.1 percentage points of the true population percentage. Complete parts (a) through (c) below. a. Assume that nothing is known about the percentage of adults who believe that passwords should be replaced with biometric security. The sample size needed is (Round up to the nearest whole number as needed.) b. Assume that a prior survey suggests that about 46% of adults believe that biometric security should replace passwords. The sample size needed is (Round up to the nearest whole number as needed.) c. Does the additional survey information from part (b) have much of an effect on the sample size that is required? The additional survey information from part (b) causes the required sample size to change by V 10%. Based on…

Gaining admittance into medical school is a difficult task. Researchers want to know if more students who complete a graduate degree gain admission into medical school than those who do not. They compare the number of students who were admitted who had a master's degree with those who did not. A detailed analysis of the data is carried out to arrive at a conclusion. What type of a research study is this? O a survey O an experiment O an observational study O a controlled study
Please answers questions a through d. Thank you!
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 39% with a margin of error of 1.3%. Describe the conclusion about p using an absolute value inequality. The answer field below uses the symbolic entry option in Mobius. 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%).
