- A Researcher Wishes To Estimate The Proportion Of X Ray Machines That Malfunction A Random Sample Of 175 Machines Is Ta 1 (24.47 KiB) Viewed 38 times
A researcher wishes to estimate the proportion of X-ray machines that malfunction. A random sample of 175 machines is taken, and 56 of the machines in the sample malfunction. Based upon this, compute a 90% confidence interval for the proportion of all X-ray machines that malfunction. Then find the lower limit and upper limit of the 90% confidence interval. EO Carry your intermediate computations to at least three decimal places. Round your answers to two decimal places. (If necessary, consult a list of formulas.) Lower limit: 1 Upper limit: 1 Х 5 ? 2
