Step 1
Step 1: Calculate the expected value of x using the formula E(x) = Σ(x * P(x)), where x represents the number of times a customer visits the store and P(x) is the probability of x. Show more…

Let x represent the number of times a person visits a grocery store in a 1-week period. Assume the following is the probability distribution of x. X P(X) 0 .1 1 .5 2 .3 3 .1 Calculate the average number of times a person visits the store in 1 week. Calculate the variance and standard deviation of this distribution. What is the probability that a person will visit the grocery store at least 2 times in a 1-week period?

A small store keeps track of X = the number of customers who make a purchase during the first hour that the store is open each day. Based on the records, X has the following probability distribution: Value of X 0 1 2 3 4 Probability 0.3 0.2 0.3 0.1 0.1 What is the standard deviation of the number of customers who make a purchase during the first hour that the store is open?
Use the following information to answer the next ten exercises. A customer service representative must spend different amounts of time with each customer to resolve various concerns. The amount of time spent with each customer can be modeled by the following distribution: $X \sim Exp(0.2)$ State the probability density function.
