Suppose it is known that the mean number of runs scored by the White Sox last season is 3.8, with a standard deviation of 1.2 and the mean number of runs scored by the Astros last season is 4.1, with a standard deviation of 1.6. Suppose you watched 30 games from each team last season and calculated the mean for the games you watched for each team. Which of these can be used to approximate the probability that out of the games watched, the mean number of runs scored for the Astros was at least 1 run higher than the White Sox? There may be more than one answer so select all that apply. Group of answer choices
a) normalcdf(-9999, -1, -0.3, 0.365)
