Transcribed Image Text:Find the indicated value. 9) 225 individuals who complained of chronic pain were randomly assigned to three daily treatments: three tablets of Brand A (prescription drug), three tablests of Brand B (non-prescription drug), or three placebos. Each subject was questioned to determine the 9) 4) Assume that the weights of quarters are normally distributed with a mean of 5.67 g and a standard deviation 0.070 g. A vending machine will only accept coins weighing between 5.48 g and 5.82 g. What percentage of legal quarters will be rejected? A) 2.48% 4) effectiveness of their treatment. Find x2a the x2 critical value based on a 0.01 significance level. B) 1.94% C) 1.62% D) 0.0196% Brand A Brand B Placebo Solve the problem. Relief from 5) A 99% confidence interval (in inches) for the mean height of a population is 65.64 < µ < 67.16. This result is based on a sample of size 144. If the confidence interval 65.85 < µ < 66.95 is obtained from the same sample data, what is the degree of confidence?
