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 data obtained follow Excel File: data 16-21.xls Paint 1 128 137 135 Paint 2 144 133 142 146 130 Paint 3 133 143 137 136 131 Paint 4 150 142 135 124 140 141 153 a. Use a = .05 to test for any significant differences in mean drying time among the paints. If an amount is zero, enter "0".
