Problem 1. A politician is interested how voters in her district feel about gun control. She surveyed 175 voters and found that 96 support gun control. She wants to estimate the proportion of all voters in her district who support gun control with a 95% confidence interval. (a) (2 points) Find the point estimate. (b) (2 points) Verify that the conditions for inference are satisfied. (c) (2 points) Construct the confidence interval for estimating the population proportion. Interpret your results....

A company says that its product has a 95% positive approval rating. A polling company found that 89% of 500 people surveyed approved of the product. Construct a 90% proportion confidence interval based on this data and determine whether the data supports the 95% positive approval rating claim. Start by using the binomial distribution (p + q)n = 1, and x = np. Use Summary 5b, Table 1, Column 3. What is n? What is p? What is q? What...

A poll done for an organization found that 13% of Americans have seen or sensed the presence of an angel. A contingent doubts that the percent is really that high. It conducts its own survey. Out of 73 Americans surveyed, only two had seen or sensed the presence of an angel. As a result of the contingent's survey, would you agree with the organization's poll? Conduct a hypothesis test at the 5% level. What is the test statistic? What is...

a) Approximately 500 students take a particular college statistics course each year. As an exercise, each of the 500 students in the class is given a different random sample of the previous year's 500 final grades (in percentages) and asked to construct a 95% interval estimate of the previous year's overall average. Which of the following statements is correct? About 475 of the confidence intervals will contain the actual overall average for the previous year. It is probable that 475...
