To find the difference of the means, we first need to find the mean of each set of data.
For the baseball team data:
Total number of pets = 0 + 0 + 0 + 1 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 4 = 24
Number of students on the baseball team = 15
Mean of baseball team data = Total number of pets / Number of students on the baseball team
Mean of baseball team data = 24 / 15
Mean of baseball team data = 1.6
For the French club data:
Total number of pets = 0 + 0 + 1 + 1 + 1 + 2 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 6 = 31
Number of students in the French club = 15
Mean of French club data = Total number of pets / Number of students in the French club
Mean of French club data = 31 / 15
Mean of French club data = 2.07
The difference of the means = Mean of French club data - Mean of baseball team data
Difference of the means = 2.07 - 1.6
Difference of the means = 0.47
Therefore, the difference of the means of the two sets of data is 0.47, which is not one of the given options.
students on the baseball team and in the French club were asked how many pets they have. The results are shown.
Baseball team: 0,0,0,1,1,1,1,1,2,2,2,3,3,3,4
French club: 0,0,1,1,1,2,2,2,2,3,3,3,3,4,6
what is the difference of the means of the two sets of data?
a 0.6
b 1
c 1.9
d 2
