1a) Manual Transmission Automobiles In 1980 more than 35% of cars purchased had a manual transmission (i.e. stick shift). By 2007 the proportion had decreased to 7.7%. A random sample of college students who owned cars revealed the following: out of 130 cars, 24 had stick shifts. Estimate the proportion of college students who drive sticks with 90% confidence. Use a graphing calculator and round the answers to at least three decimal places. b) Belief in Haunted Places A random sample of 305 college students were asked if they believed that places could be haunted, and 44 responded yes. Estimate the true proportion of college students who believe in the possibility of haunted places with97% confidence. According to Time magazine, 37% of Americans believe that places can be haunted.

You are interested in constructing a 99% confidence interval for the proportion of all caterpillars that eventually become butterflies. Of the 431 randomly selected caterpillars observed, 50 lived to become butterflies. Round answers to 4 decimal places where possible. a. With 99% confidence the proportion of all caterpillars that lived to become a butterfly is between___ and___ . b. If many groups of 431 randomly selected caterpillars were observed, then a different confidence interval would be produced from each group. About____ percent of these confidence intervals will contain the true population proportion of caterpillars that become butterflies and about ____ percent will not contain the true population proportion.
On the day before an election in a large city, each person in a random sample of 1,000 likely voters is asked whichcandidate he or she plans to vote for. Of the people in the sample, 55 percent say they will vote for candidateTaylor. A margin of error of 3 percentage points is calculated. Which of the following statements is appropriate?(A)The proportion of all likely voters who plan to vote for candidate Taylor must be the same as the proportionof voters in the sample who plan to vote for candidate Taylor (55 percent), because the data were collectedfrom a random sample.(B) The sample proportion minus the margin of error is greater than 0.50, which provides evidence that morethan half of all likely voters plan to vote for candidate Taylor.(C)It is not possible to draw any conclusion about the proportion of all likely voters who plan to vote forcandidate Taylor because the 1,000 likely voters in the sample represent only a small fraction of all likelyvoters in a large city.(D) It is…

Suppose 500 different researchers all randomly select samples of n = 300 individuals from a population. Each researcher uses his or her sample to compute a 95% confidence interval for the proportion who have blue eyes in the population. About how many of the confidence intervals will cover the population proportion? About how many of the intervals will not cover the population proportion? Briefly explain how you determined your answers. About About which is % of the 500 computed intervals, should contain the population proportion. which is % of the 500 computed intervals, should not contain the population proportion.
