Four different paints are advertised as having the same drying time. To check the manufacturer's 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. The following data were obtained.

Paint 1 Paint 2 Paint 3 Paint 4

128 144 133 150

137 133 143 142

135 142 137 135

124 146 136 140

141 130 131 153
