Chapter 11, Problem 59SE

The bond strength when mounting an integrated circuit on a metalized glass substrate was studied as a function of factor A 5 adhesive type, factor B 5 curve time, and factor C 5 conductor material (copper and nickel). The data follows, along with an ANOVA table from Minitab. What conclusions can you draw from the data?

A history teacher interviewed a random sample of 80 students about their preferences in learning activities outside of school and whether they are considering watching a historical movie at the cinema.  69 answered that they would like to go to the cinema. Let p represent the proportion of students who want to watch a historical movie. Determine the maximal margin of error. Use α = 0.05. Round your answer to three decimal places. ​
A random sample of medical files is used to estimate the proportion p of all people who have blood type B. If you have no preliminary estimate for p, how many medical files should you include in a random sample in order to be 99% sure that the point estimate  will be within a distance of 0.07 from p? Round your answer to the next higher whole number.
A clinical study is designed to assess the average length of hospital stay of patients who underwent surgery. A preliminary study of a random sample of 70 surgery patients’ records showed that the standard deviation of the lengths of stay of all surgery patients is 7.5 days. How large should a sample to estimate the desired mean to within 1 day at 95% confidence? Round your answer to the whole number.
