Three different paints were advertised as having the same dry time. To check manufacturer's claim, five random samples of each paint are taken (5 cans of each paint). The dry times in minutes (until ready to apply second coat) were recorded. At alpha of 0.05, test to see whether the mean drying time is the same for each type of paint. What is your conclusion?

Note: Please explain it in excel along with excel formulas. Thanks
