Question: Throughout the 1980's, the San Francisco Giants baseball team was known for something called their "June Swoon", where they don't do quite as well in June as they have up to that point. The data below represent the number of runs the San Francisco Giants scored per game during two different ten game stretches during the 1985 season, one in A^pril and one in June.

Is there evidence to indicate a difference in the number of runs scored per game between the two months, with 95% confidence? Assume the numbers of runs per game scored by the Giants are normally distributed. (You will need to use two confidence intervals.)
