Question: 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.

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 1:128,137,135,124,141

Paint 2: 144,133,142,146,130

Paint 3: 133,143, 137, 136, 131

Paint 4: 150, 142, 135. 140, 153

At the .05 level of significance, test to see whether the mean drying time is the same for each type of paint.
