Robert Klassan Manufacturing, a medical equipment manufacturer, subjected 90 heart pacemakers to 4,000 hours of testing. Halfway through the testing, 6 pacemakers failed. The failure in terms of: A.) Percent of Failures =?% (enter your response as a percentage rounded to one decimal place) B.) Number of Failures per unit-hour= ? Failures per hour (round your response to eight decimal places). C.) Number of Failures per unit-hear= ? Failures per year (round your response to four decimal places) D.) If 1,100 people receive pacemaker implants, how many units can we expect to fail during the following year? Number of Failures= ? failures (round your response to two decimal places). This was an example problem given to me. I have a test with a similar question in April. Any explanation would be greatly appreciated.
