Question

Suppose a large chain of home improvement stores has a computer located near the front entrance of each of their stores to allow prospective employees to submit employment applications. Suppose that between the hours of 9 a.m. and 12 noon on non-holiday weekdays, people arrive at the computer to submit applications uniformly, and that the mean time each computer sits idle is 10 min. Determine the probability that on a random non-holiday weekday, the computer will sit idle for more than 15 min during the hours of 9 a.m. and 12 noon. Give your answer in decimal form, precise to three decimal places.

Probability=

Answer 1

Mean (u) = lo mints in An exponential distri bulin da do to Per minute PCX*X) - I-et PCX78) = 1-[-e-te] S PCXD15) - 1-[i-e-AXIS) P(x215) - e-tomis P(xxls) -1.5 P(x715) = 0.22313 so Probability of completes during 9; am and 12 noon than 15 minutes is sit idle for more 10.223 l
