A trade magazine routinely checks the drive-through service times of fast-food restaurants. A 95% confidence interval that results from examining 502 customers in one fast-food chain's drive-through has a lower bound of 165.9 seconds and an upper bound of 169.5 seconds. What does this mean? Choose the correct answer below. O A. One can be 95% confident that the mean drive-through service time of this fast-food chain is 167.7 seconds. O B. There is a 95% probability that the mean drive-through service time of this fast-food chain is between 165.9 seconds and 169.5 seconds. O C. One can be 95% confident that the mean drive-through service time of this fast-food chain is between 165.9 seconds and 169.5 seconds. O D. The mean drive-through service time of this fast-food chain is 167.7 seconds 95% of the time.

A Surprising fact indicates that a small proportion of teens use a password on their mobile device. A poll chooses a simple random sample of 120 teens and asks if they use a password on their mobile device. The results showed that 56 of teens in our sample used a password on their mobile device. Find a 90 % confidence interval for the proportion of teens who use a password on their mobile device. Interpret your confidence interval.

Chapter 8. 5) A random sample of 43 Foreign Language movies made since 2000 had a mean length of 112.5 minutes, with a standard deviation of 12.6 minutes. (a) Construct a 95% confidence interval for the true mean length of all Foreign Language movies made since 2000 (b) As of November 2010, three Spider-Man movies have been released, and their mean length is 129 minutes. Someone claims that the mean length of Spider-Man movies is actually less than the mean length of all Foreign Language movies. Does the confidence interval contradict this claim? 6
Several years ago, 44% of parents who had children in grades K-12 were satisfied with the quality of education the students receive. A recent poll asked 1,075 parents who have children in grades K-12 if they were satisfied with the quality of education the students receive. Of the 1,075 surveyed, 479 indicated that they were satisfied. Construct a 95% confidence interval to assess whether this represents evidence that parents' attitudes toward the quality of education have changed. What are the null and alternative hypotheses? Ho: p = 0.44 versus H,: p 0.44 (Round to two decimal places as needed.) Use technology to find the 95% confidence interval. The lower is The upper bound is (Round to two decimal places as needed.)

A learn-to-type software program claims that it can improve your typing skills. To test the claim and possibly help yourself out, you and six of your friends decide to try the program and see what happens. Use the table below to construct an 80% confidence interval for the true mean change in the typing speeds for people who have completed the typing program. Let Population 1 be the typing speed before taking the program and Population 2 be the typing speed after taking the program. Round the endpoints of the interval to one decimal place, if necessary.

A survey of 32,782 adults in 2004 indicated that 24.6% of adults were current smokers. A similar study conducted in 1995 of 40,000 adults indicated that 29.7% were current smokers. a. Find and interpret a point estimate of the difference between the proportion of current smokers in 1995, and the proportion of current smokers in 2004. b. A 95% confidence interval for the true difference is (-0.058,-0.045). Interpret. c. What assumptions must you make for the confidence interval i part b to be valid? (…) a.
