Solution We have have given the 95% confidence interval.

A student was asked to find a 95% confidence interval for widget width using data from a random sample of size n = 18. Which of the following is a correct interpretation of the interval 12 <µ < 34.8? Check all that are correct. With 95% confidence, the mean width of a randomly selected widget will be between 12 and 34.8. With 95% confidence, the mean width of all widgets is between 12 and 34.8. The mean width of all widgets is between 12 and 34.8, 95% of the time. We know this is true because the mean of our sample is between 12 and 34.8. O There is a 95% chance that the mean of the population is between 12 and 34.8. O There is a 95% chance that the mean of a sample of 18 widgets will be between 12 and 34.8.

The ages of a group of 137 randomly selected adult females have a standard deviation of 16.5 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 16.5 years for the sample size calculation. How many female statistics student ages must be obtained in order to estimate the mean age of all female statistics students? Assume that we want 90% confidence that the sample mean is within one-half year of the population mean. The required sample size is (Type a whole number.)

A clinical trial was conducted to test the effectiveness of a drug for treating insomnia in older subjects. Before treatment, 18 subjects had a mean wake time of 100.0 min. After treatment, the 18 subjects had a mean wake time of 75.7 min and a standard deviation of 20.4 min. Assume that the 18 sample values appear to be from a normally distributed population and construct a 95% confidence interval estimate of the mean wake time for a population with drug treatments. What does the result suggest about the mean wake time of 100.0 min before the treatment? Does the drug appear to be effective? Construct the 95% confidence interval estimate of the mean wake time for a population with the treatment. min<μ
The breaking strengths of cables produced by a certain manufacturer have a mean, μ, of 1900 pounds, and a standard deviation of 55 pounds. It is claimed that an improvement in the manufacturing process has increased the mean breaking strength. To evaluate this claim, 80 newly manufactured cables are randomly chosen and tested, and their mean breaking strength is found to be 1912 pounds. Can we support, at the 0.05level of significance, the claim that the mean breaking strength has increased? (Assume that the standard deviation has not changed.) Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places, and round your responses as specified below. (If necessary, consult a list of formulas.)

In tests of a computer component, it is found that the mean time between failures is 909 hours. A modification is made which is supposed to increase reliability by increasing the time between failures. Tests on a sample of 25 modified components produce a mean time between failures of 955 hours. Using a 1% level of significance, perform a hypothesis test to determine whether the mean time between failures for the modified components is greater than 909 hours. Assume that the population standard deviation is 53 hours.

The ages of a group of 134 randomly selected adult females have a standard deviation of 18.2 years. Assume that the ages of female statistics students have less variation than ages of females in the general population, so let o = 18.2 years for the sample size calculation.
