document.write( "Question 1174466: Suppose that you are working for a chain restaurant and wish to design a promotion to disabuse the public of notions that the service is slow. You decide to institute a policy that any customer that waits too long will receive their meal for free. You know that the wait times for customers are normally distributed with a mean of 16 minutes and a standard deviation of 3.3 minutes. Use statistics to decide the maximum wait time you would advertise to customers so that you only give away free meals to at most 1% of the customers.\r

\n" ); document.write( "\n" ); document.write( "• Include a graph illustrating the solution. For the graph do NOT make an empirical rule graph, just include the mean and the mark off the area that corresponds to the 1% who would receive the refund. There is a Normal Distribution Graph generator linked in the resources area. Combine the above into as single file and upload using the link below\r
\n" ); document.write( "\n" ); document.write( "• Write a response to the vice president explaining your prescribed maximum wait time. Structure your essay as follows:
\n" ); document.write( " An advanced explanation of the normal distribution
\n" ); document.write( " Why the normal distribution might apply to this situation
\n" ); document.write( " Describe the specific normal distribution for this situation (give the mean and standard deviation)
\n" ); document.write( " Explain how the graph created in part b. represents the waiting times of the customers.
\n" ); document.write( " Explain the answer to part a. in terms of both the customers who get a free meal and those who do not. Feel free to use the accurate answer in part a to determine a \"nice\" wait time to be used in the actual advertising campaign.
\n" ); document.write( " Use the answers to parts a. and b. to explain how the proposal will not result in a loss of profit for the company.
