Suppose that a random sample of 11 adults has a mean score of 78 on a standardized personality test, with a standard deviation of 4. (A higher score indicates a more personable participant.) If we assume that scores on this test are normally distributed, find a 95% confidence interval for the mean score of all takers of this test. Then complete the table below. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)

Thelma and Louise are each attempting to estimate the proportion of adults who enjoy listening to country music. They each survey a different random sample of adults, and in each sample, the proportion who say they enjoy listening to country music is 0.29. Thelma and Louise each use their sample data to construct a confidence interval. Thelma's interval is from 0.242 to 0.338 and Louise's interval is from 0.237 to 0.323. One of these intervals was computed correctly and the other was not. Which interval must be the correct one? It's impossible to answer this question without knowing the level of confidence used for each interval. It's impossible to answer this question without knowing the sample sizes. O It's impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval. Thelma's interval must be the correct interval. O Louise's interval must be the correct interval.
each item # 7-8. 7. Researchers study the effect of political commercials and the likelihood of people inspired to vote for former President Trump in the 2024 presidential election. They show a political commercial to a random sample 150 people. The researchers found a 90% confidence interval for the proportion of people who were influenced to vote for former President Trump after viewing the political commercial to be (0.56, 0.72). Which is true based on the given confidence interval? Select the two correct answers. e. a. We are 90% confident that the true proportion of people inspired to vote for former President Trump after viewing a political commercial is between 0.56 and 0.72. b. 90% of all 90% confidence intervals constructed in this way will capture the true proportion of people inspired to vote for former President Trump after viewing a political commercial. c. We're 90% sure that the proportion of people in this research sample inspired to vote for Sve former President Trump…
