Examine the seven practice laps from the table below. Determine whether the mean lap time is statistically the same for the seven practice laps, or if there is at least one lap that has a different mean time from the others. (Use a signicance level of 0.05. Let 1 = Lap 1, 2 = Lap 2, 3 = Lap 3, 4 = Lap 4, 5 = Lap 5, 6 = Lap 6, and 7 = Lap 7.)
