Grantham University Statistics Worksheet

Each  week, you will be asked to respond to the prompt or prompts in the  discussion forum. Your initial post should be 75-150 words in  length, and is due on Sunday. By Tuesday, you should respond to two  additional posts from your peers.

For the last several weeks, you have been working with this scenario:

ABC  Enterprises is a company in which employees must frequently travel for  business meetings with clients inside their city limits. Currently, each  employee is allotted 40 dollars each day to cover meals while on the  road.  They are reimbursed for gas and other expenses in a separate  budget, so the 40 dollars is only for meals. Employees have complained  that this amount is not enough, especially if they had several meetings  per day, and HR wanted to investigate.  A survey was given to get  recommendations for a new daily meal allotment.  Although not all  responded, 49% of employess did.

Open the spreadsheet. There is more data now.

Answer these questions and explain what you did to solve each one.  (include your calculations.)

If one survey response was randomly selected, what is the probability that it was given by someone over 39 years of age?

If  two responses were randomly selected, one at a time, without  replacement, what is the probability that both were given by a male?

What is the probability that a selection was over 55 dollars, given that it was a response from a female?

Search  the internet for an article published in the last 18 months on how  businesses use probability.  Provide the title, author, and the URL.   Provide a four-sentence summary of how probability is used in business.   Cite your source in APA format.
