Squirt Squad is a cleaning service that sends crews to residential homes on either a once a month or a twice a month schedule, depending on the customer’s preference. The owner would like to predict the amount of time, in minutes, required to clean a house based on the square footage of the house, the total number of rooms in the house, the number of bathrooms it has, and the size of the cleaning crew. Data from randomly selected homes can be found in the Excel file Squirt Squad 1.xlsx.
