7. Suppose P(Z > z) = 0.9656. What is the value of z? Round your answer to 2 decimal places.

8. Let X be the number of shoppers in a supermarket line in an hour. Assume each person is independent. What type of probability distribution does X follow?

		A general discrete distribution
		A binomial distribution
		A Poisson distribution
		An exponential distribution

Expert Solution

#7.

z = -1.82

P(Z > -1.82) = 0.9656

area to the left of z is 1 - 0.9656 = 0.0344

Using left tailed z-table

#8.

This is Poisson's distribution
