Question During the 2018 major league baseball season, the Chicago Cubs scored an average of 5.2 runs per game during 46
randomly selected games with a known standard deviation of 0.7 runs per game. The Atlanta Braves scored 5.1 runs per
game on average during 48 randomly selected games with a known standard deviation of 0.6.
Is there enough evidence, ata a -0.01 level of significance, to say the Cubs score more runs per game than the Braves, on
average?
