Problem 1.70 The two portions of member AB are glued together along a plane forming an angle ? with the horizontal. Knowing that the ultimate stress for the glued joint is 2.5 ksi in tension and 1.3 ksi in shear, determine the range of values of ? for which the factor of safety of the members is at least 3.0.

Leakage from underground fuel tanks has been a source of water pollution. In a random sample of 87 gasoline stations, 13 were found to have at least one leaking underground tank.
a. Find a 95% confidence interval for the proportion of gasoline stations with at least one leaking underground tank. b. How many stations must be sampled so that a 95% confidence interval specifies the proportion to within ±0.03?
The article “The Prevalence of Daytime Napping and Its Relationship to Nighttime Sleep” presents results of a study of sleep habits in a large number of subjects. In a sample of 87 young adults, the average time per day spent in bed (either awake or asleep) was 7.70 hours, with a standard deviation of 1.02 hours, and the average time spent in bed asleep was 7.06 hours, with a standard deviation of 1.11 hours. The mean time spent in bed awake was estimated to be 7.70–7.06=0.64 hours. Is it possible to compute a 95% confidence interval for the mean time spent in bed awake? If so, construct the confidence interval. If not possible, explain why not.
