A pizza delivery service captures information related to each delivery, for example the delivery time, the temperature of the pizza, the name of the driver, the date of the delivery, the name of the branch, and many more. The pizza delivery service data is available on Canvas > Data pizza.csv file. (a) Plot the sales amount (using the variable bill) sold by each branch by day of the week. You can use any graph you like. (b) Calculate the average sales amount (using the variable bill) by day of the week for each branch. (c) Assess the normality of the variable, time. What did you find? (d) Construct histograms for pizza delivery time (variable time) and add a normal curve along with the histogram. (e) Generate horizontal box plots that show the distribution of pizza delivery time (variable time) stratified by branch (variable branch). pizza.csv↓
