1. the operations manager of a large production plant would like to estimate the mean amount of time a worker takes to assemble a new electronic component. assume that the standard deviation of this assembly time is 3.6 minutes. i. after observing 120 workers assembling similar devices, the manager noticed that their average time was 16.2 minutes. construct a 92% confidence interval for the mean assembly time. x¯ ± z0.96 √σ n ii. how many workers should be involved in this study in order to have the mean assembly time estimated up to 15 seconds with 92% confidence? e = z0.96 √σ n where e = 0.25 minutes.

Lockheed martin, the defense contractor designs and build communication satellite systems to be used by the u.s. military. because of the very high cost the company performs numerous test on every component. these test tend to extend the component assembly time. suppose the time required to construct and test (called build time) a particular component is thought to be normally distributed, with a mean equal to 45 hours and a standard deviation equal to 6.75 hours. to keep the assembly flow moving on schedule, this component needs to have a build time between 37.5 and 54 hours. find the propability that the bulid time will be such that assembly will stay on schedule.

The palmer high school junior civitans club is to build a play area for the kindergarten classes as their service project. leah, the club president, needs to send club members to build and paint the last set of swings but isn’t sure how many workers are needed. she knows that the length of time it takes to build and paint a set of swings is inversely proportional to the number of workers and that the previous week it took 6 workers 15 hours to build and paint a set of swings. how many workers should maddie send to build and paint the last set if they only have nine hours available in which to work? be sure to show each step leading to the solution. write a brief statement explaining why the number of workers should be rounded to the nearest whole number and which rounding is correct--rounding the solution up or rounding the solution down.
