Suppose that the length of research papers is uniformly
distributed from 10 to 24 pages. We survey a class in which 55
research papers were turned in to a professor. We are interested in
the average length of the research papers.
Give the distribution of
X.

A manufacturer produces 25-pound lifting weights. The lowest actual weight is 24 pounds, and the highest is 26 pounds. Each weight is equally likely so the distribution of weights is uniform. A sample of 100 weights is taken. a. What is the distribution for the weights of one 25-pound lifting weight? What is the mean and standard deviation? b. What is the distribution for the mean weight of 100 25-pound lifting weights? c. Find the probability that the mean actual...

Q.24.A sample of 55 research cotton samples resulted in a sample average percentage elongation of 8.11 and a sample standard deviation of 1.46. Calculate a 95% large-sample CI for the true average percentage elongation μ. (Round your answers to three decimal places.) What assumptions are you making about the distribution of percentage elongation? We make no assumptions about the distribution of percentage elongation. We assume the distribution of percentage elongation is normal with the value of σ unknown. We assume...
