Paper Instructions

Unit 5, Chapter 5 LabComplete all problems using Excelwhen appropriate as explained. These exercises are intended for you to learn how to use the Excel to compute Binomial and Poisson probabilities and to also understand how the cumulative function works. You are to submit one file with each answer on a separate tab as defined below (therefore you will have four separate tabs). Your Excel file should be saved using file naming convention as last name first initial Unit 5 Lab. Proper naming format is also as part of your lab grade.

Problem 1, tab 1. Construct Binomial probability in Excel for Martin Cloths.Using the probability equation;=BINOM.DIST(number success, Trials, Probability, cumulative), where number successes = the # successes for the problem, Trials = n, Probability = p, and cumulative where using T means show the cumulative probability for the value of x or fewer, and F means probability of exactly x successes. Note, the sum of F will equal 1 and T values will be cumulative with the last value equal to 1.

You will create a table as shown below using x values 0 – 3 to represent the number of customers that we are interested in determining the probability of a sale. For this problem, n = 3 and p = .30 which means there are three trials with a probability of success 30%. The table will include using cumulative of False in one column and True in the other, to help learning the differences between the two functions. You will also calculate E(x), Var, and StdDev using np for E(x), np(1-p) for Variance and SQRT of Var respectively. Youranswer in the False column should be the same as the chapter notes we discussed and as shown in table 5.13.

Problem 2, tab 2. Construct Poisson Excelformula, =Poisson(x, mean, cumulative) for cars arriving at drive-up window. The average number of cards arriving in any 15-minute period = 10, therefore

u= 10.This is a problem we did manually in the lecture where we solved for x of 5. However, for this lab assignment you will find Poisson for x from 0-20, meaning your column will showx values for arrivals listed 0 – 20 and calculate the Poisson for each these arrival times. In this table you want to determine the probability of arrival times for each arrival time. Based on this objective, determine whether you should use cumulative of True or False with the answers and explain your reason. Also include a 2-D column chart of the data.

Problem 3, tab 3. A Randstad/Harris interactive survey reported that 25% of employees said that theircompany is loyal to them (USA Today, November 11, 2009).Suppose 10 employees

are selected randomly and will be interviewed about company loyalty.Note, this is a binomial problem because it is asking to determine the number of successes. Answer the following and use Excel binomial equationwhere appropriate.=Binom.Dist(number_s, trials, probability_s, cumulative) where number_s = number of successes, trials = n, probability_s = probability, cumulative = either True or False.

(a) Is the selection of 10 employees a binomial experiment (does it meet the conditions for a binomial probability)? Explain.

(b) What is the probability that none of the 10 employees will say their company is

loyal to them?

(c) What is the probability that 4 of the 10 employees will say their company is loyal

to them?

(d) What is the probability that at least 2 of the 10 employees will say their company

is loyal to them? Remember from problem we did in class, with “at least” we manually calculated the cumulative value and subtract the sum from 1. This will provide the difference between all probabilities (sum = 1) and the cumulative “at least” quantities. So, in this case you want the cumulative values for 0 and 1 subtracted from 1 to show 2 of the 10. Therefore, for this problem you will use =1-Binom.Dist(number_s, trials, probability_s,cumulative)

(e) What is the expected number of employees (out of 10 employees) who will say

their company is loyal to them?

(f) What is the variance on the number of employees (out of 10 employees) who will

say their company is loyal to them?

Problem 4, tab 4. More than 50 million guests stay at bed and breakfast (B&Bs) each year. The website for the Bed and Breakfast Inns of North America, which averages seven visitors per

minute, enables many B&Bs to attract guests. Use Excel equations to complete all questions where appropriate. Poisson calculation in Excel is =Poisson.Dist(x,mean, cumulative) where x = the number of occurrences, mean = self-explanatory, may be shown as

u, cumulative = either True or False.(a) Compute the probability of no website visitors in a one-minute period.

(b) Compute the probability of two or more website visitors in a one-minute period. You should follow the same logic used in 3d by finding

>. Therefore use =1-=Poisson.Dist(x,mean,cumulative)(c) Compute the expected number of website visitors in a one-minute period.

(d) Compute the variance of the number of website visitors in a one-minute period. Recall in the lecture and PowerPoint notes regarding the mean and variance for Poisson distributions.
