Project Description:
You have been hired to analyze the effectiveness of a local restaurantās drive-through service. As part of your analysis, you will evaluate customer satisfaction. You hypothesize that customer satisfaction decreases as wait time increases. You also believe there is a correlation between the quality of the food and overall satisfaction. You have collected a cross-section sample of 30 customersā wait time and satisfaction level surveys based on the range of 1 to 5, with 1 being least satisfied and 5 being most satisfied. You have also pulled a random sample of 10 surveys to evaluate wait time satisfaction.

Anew author is in the process of negotiating a contract for a new romance novel. the publisher is offering three options. in the first option, the author is paid $5,000 upon delivery of the final manuscript and $20,000 when the novel is published. in the second option, the author is paid 12.5% of the net price of the novel for each copy of the novel sold. in the third option, the author is paid 10% of the net price for the first 4,000 copies sold, and 14% of the net price for the copies sold over 4,000. the author has some idea about the number of copies that will be sold and would like to have an estimate of the royal- ties generated under each option. write a program that prompts the author to enter the net price of each copy of the novel and the estimated number of copies that will be sold. the program then outputs he royalties under each option and the best option the author could choose. (use appropriate named constants to store the special values such as royalty rates and fixed royalties.
