The pressures obtained from a manufacturing process of capillary tubes is found to be normally distributed with an average pressure of 130 pounds per square inch and a standard deviation of 4 pounds per square inch. Determine: a) What percent of the pressures are below 121 pounds per square inch? b) What percent of the pressure readings lie between 121 and 134 pounds per square inch?

**Assignment Instructions** **After showing all steps of your work on paper, scan as a PDF file and upload it to this assignment.** ### Problems: 1) The acceptability of a capillary tube for a freezer application is found by measuring the pressure drop in pounds per square inch between the two ends of the tube. The pressures obtained from a manufacturing process of capillary tubes is found to be normally distributed with an average pressure of 130 pounds per square inch and a standard deviation of 4 pounds per square inch. Determine: a) What percent of the pressures are below 121 pounds per square inch? b) What percent of the pressure readings lie between 121 and 134 pounds per square inch? 2) It is estimated that 3.5% of the general population will live past their 90th birthday. In a graduating class of 753 high school seniors, what is the probability that a) 30 or more will live beyond their 90th birthday? b) More than 40 will live beyond their 90th birthday? 3) The time in hours during which an electrical generator is operational is a random variable that follows an exponential distribution. If the average operational time is 160 hours, what is the probability that a generator of this type will be operational between 60 and 160 hours? **Instructions for Submission:** - After solving each problem, show all steps and calculations on paper. - Scan the completed work as a single PDF file. - Upload the PDF file to this assignment submission portal. **Navigation:** [◀ Previous ] [ Next ▶]
