Develop an empirical bivariate probability distribution for number of snack items and the number of reading materials in a randomly selected customer purchase. Find the probability of a customer purchase consisting of one item of reading materials and two snack items, probability of a customer purchasing one snack item and to explain why the probability, f ( x = 0 , y = 0 ) = 0 .

Solutions

Chapter 5, Problem 62SE

a.

To determine

Develop an empirical bivariate probability distribution for number of snack items and the number of reading materials in a randomly selected customer purchase.

Find the probability of a customer purchase consisting of one item of reading materials and two snack items, probability of a customer purchasing one snack item and to explain why the probability, f(x=0,y=0)=0.

b.

To determine

Show the marginal probability distribution for the number of snack items purchased and compute its expected value and variance.

c.

To determine

Compute the expected value and variance for the number of reading materials purchased by a customer.

d.

To determine

Show the probability distribution for total number of items in a customer purchase and to compute its expected value and variance.

e.

To determine

Compute the covariance and correlation coefficient between x and y.

Identify the relationship between the number of reading materials and the number of snacks purchased on a customer visit.
