9 Four different paints are advertised as having the same drying time. To check the manufacturers' claims, five samples were tested for each of the paints. The time in minutes until the paint was dry enough for a second coat to be applied was recorded for each sample. The dataobtained follow.Excel File: data16-21.xlsPaint 1Paint 2Paint 3Paint 4128144133150137133143142135142137135124146136140141130131153 a. Use a = 0.05 to test for any significant differences in mean drying time among the paints. If your answer is zero, enter "0".Lets define the dummy variables as follows:D1D2D3Paint1111Regression StatisticsMultiple R (to 4 decimals)R Square (to 4 decimals)Adjusted R Square (to 4decimals)Standard Error (to 4decimals)Observations (to wholenumber)ANOVAdfMSFSignificance(to whole(to whole(to 2(to 4Fnumber)number) decimals) decimals)(to 4decimals)RegressionResidualTotalCoefficients Standard t StatP-value(to wholeError(to 4(to 4number)(to 4decimals) decimals)decimals)InterceptD1D2D3At the 0.05 level of significance,Select your answerНо-b.
