The average attendance will be (0.696)(2) = 1.392 standard deviations above average. If a team is 1 standard deviation below average in attendance, what would you predict about the number of games the team has won? The number of games the team has won will be (0.696)(1) = 0.696 standard deviations below the average wins.
