A bar can have only six barstools. Customers interested in having a drink at this bar arrive at a rate of 6 per hour following a Poisson distribution. It is expected that a customer stays 30 minutes, exponentially distributed. There are only 3 spaces available for customers to wait for a barstool to become available. Customers who want to come in and find there is no room to wait, go to the restaurant next door. Determine:

a. Probability that there are no customers at the bar.

b. The probability that an arriving customer has to wait for a barstool.

c. The average number of customers at the bar.

d. The average number of customers waiting.

Suppose I own a store and am only interested in increasing the number of potential customers...

Suppose I own a store and am only interested in increasing the number of potential customers that enter my store. Further, I believe that advertising could influence how many people enter my establishment. Based on past experience with similar stores, I estimate the following relationship between the number of customers (C) and the amount of advertising (A) to be: C = 100 + 6A – A²/100. a. Graph this function and describe (in economic terms!) the intercept and slope. b....

A candy bar manufacturer is interested in estimating sales using price of the candy bar in different cities. To do this the manufacturer randomly selected 7 small cities and offered the candy at different price. Using candy bar sales as dependent variable, the manufacturer will conduct simple regression using the data below: Price (X) Sales (Y) XY X² Y² 1.3 100 130 1.69 10000 1.6 90 144 2.56 8100 1.8 90 162 3.24 8100 2 40 80 4 1600 2.4 38...

An offline retail store called CoolStore have customers that are either students or not. Customers can buy a plastic bag or not. We know for a fact that: Twenty-five percent of all customers are students. Among customers that are students, eighty percent buy a plastic bag. Among customers who buy a plastic bag, fifty percent are students. Forty customers are chosen at random. The probability is one percent that the number of customers buying a plastic bag exceeds what number?
