Suppose that a home builder is approached by a customer who wants to move in as soon as possible. The customer chooses three home designs that she likes and asks the home builder which one could be completed the fastest. To compare the three designs on speed of completion, the builder randomly selects 10 homes that he built in the past based on each of the three designs.
Use the Excel Analysis ToolPak to run an ANOVA test in order to determine which design would be best for the customer. Show all of your work and clearly label each of your calculations. Make sure to also clearly describe the respective data and your conclusions.
The data for the number of days to build each home are as follows:
a. Design A: 15, 17, 19, 21, 23, 25, 27, 29, 31, 33
b. Design B: 29, 34, 39, 44, 49, 54, 59, 64, 69, 74
c. Design C: 22, 24, 25, 27, 28, 28, 29, 31, 33, 34
