As in most professional sports,statistics are collected in the National Hockey League.In the 2006-2007 season,teams played 82 games.A team was awarded 2 points for a win and 1 point if the game was tied at the end of regulation time but then lost in overtime.For each of the 30 teams,data on the number of goals scored per game (Goals/G) and the percentage of the 164 possible points they won (Win%) during the season were collected.The following graph shows the plotted points for the variables Win% and Goals/G and the simple linear regression line fitted using least squares. From the computer output for the least-squares fit,the estimated equation was found to be
,
= 0.398,and
= 60.29.Also,it was determined from the output that
= 12.800 and
= 4.418. If a test of hypothesis were conducted of H0:
= 0 against Ha:
0,what would be the value of the test statistic?
