In a study of intelligence, the time (in seconds) for a laboratory animal to reach a reward in a maze was found to have a probability density function
f(t) =
8
t 2
, t ≥ 8
where 8 seconds is the minimum time to traverse the maze.
(a)
Find the probability that an animal chosen at random takes between 28 and 56 seconds.

Do you dislike waiting in line? A supermarket chain has used computer simulation and information technology to reduce the average waiting time for customers at 2,300 stores. Using a new system, which allows the supermarket to better predict when shoppers will be checking out, the company was able to decrease average customer waiting time to just 23 seconds.
(a)
Assume that supermarket waiting times are exponentially distributed. Show the probability density function of waiting time at the supermarket.
f(x) =

Determine the cdf of losses for 1994 and use it to determine the probability that a 1994 loss exceeds 2,200,000.arrow_forwardWhile taking a walk along the road where you live, you accidentally drop your glove, but you don't know where. The probability density p(x) for having dropped the glove x kilometers from home (along the road) is p(x)=7e−7x for x≥0 What is the probability that you dropped it within 1 kilometer of home?arrow_forwardThe total number of hours, measured in units of 100 hours, that a family runs a vacuum cleaner over a period of one year is a continuous random variable X that has the density function shown below. Find the probability that over a period of one year, a family runs their vacuum cleaner (a) less than 120 hours; (b) between 55 and 85 hours. f(x) = x, 0<x<1 2−x, 1≤x<2 0, elsewhere A.) The probability the family runs the vacuum cleaner less than 120 hours is B.) The probability the family runs the vacuum cleaner between 55 and 85 hours isarrow_forward
