In a random sample of 23 people, the mean commute time to work was 31.7 minutes and the standard deviation was 7.2 minutes. Assume the population is normally distributed and use a t-distribution to construct a 90% confidenceinterval for the population mean p. What is the margin of error of p? Interpret the results.The confidence interval for the population mean p is(Round to one decimal place as needed.)The margin of error of u is(Round to one decimal place as needed.)Interpret the results.O A. With 90% confidence, it can be said that the commute time is between the bounds of the confidence interval.O B. If a large sample of people are taken approximately 90% of them will have commute times between the bounds of the confidence interval.O C. With 90% confidence, it can be said that the population mean commute time is between the bounds of the confidence interval.O D. It can be said that 90% of people have a commute time between the bounds of the confidence interval.

35. Which one of the following statements about a confidence interval is TRUE? The wider the confidence interval, the least precise the estimate of the population parameter The width of confidence interval is increased when the sample size is decreased. O Changes in the required level of confidence, 1-alpha, do not affect the width of the confidence interval. The width of confidence interval is increased when the sample size is increased.

A student was asked to find a 99% confidence interval for widget width using data from a random sample of size n = 24. Which of the following is a correct interpretation of the interval 12 to 33.6? The mean width of all widgets is between 12 and 33.6, 99% of the time. We know this is true because the mean of our sample is between 12 and 33.6. We are 99% confident that the mean width of a randomly selected widget will be between 12 and 33.6. There is a 99% chance that the mean of a sample of 24 widgets will be between 12 and 33.6. We are 99% confident that the mean width of all widgets is between 12 and 33.6. Which is true?

Recall that one way to express a Confidence Interval for p, is as follows: + (Margin of Error) Suppose we are given a specific interval in this form, as follows: 54.9% ± 7.4% Another way we've seen for expressing a Confidence Interval, is to write the Lower and Upper Bound values enclosed in parentheses, as follows: ( Lower Bound , Upper Bound ) We would like to take the specific interval given above, and re-express it into the second form. To do this, what specific Lower and Upper Bound values must we use? Answer: Lower Bound = __% Upper Bound =

What does the confidence interval tell about the population of all adult females? Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. O A. The results tell nothing about the population of all adult females, because participants in speed dating are not a representative sample of the population of all adult females. O B.
