A: 13 and 12 and 11
SOOOOOO the answer is......
To determine which values would increase Jesse's mean number of points, we need to calculate his current mean and compare it to the mean with each of the listed values.
Step 1: Calculate the current mean:
To find the mean, add up all the points scored and divide by the total number of games played.
12 + 15 + 14 + 12 + 4 + 8 = 65
Since there are 6 games in total, the current mean is 65 / 6 = 10.83 (rounded to two decimal places).
Step 2: Calculate the mean with each of the listed values:
We can add each listed value to the sum of points and divide by the total number of games to find the mean for each case.
Mean with 13:
65 + 13 = 78
78 / 7 = 11.14 (rounded to two decimal places)
Mean with 10:
65 + 10 = 75
75 / 7 = 10.71 (rounded to two decimal places)
Mean with 8:
65 + 8 = 73
73 / 7 = 10.43 (rounded to two decimal places)
Mean with 12:
65 + 12 = 77
77 / 7 = 11 (rounded to two decimal places)
Mean with 9:
65 + 9 = 74
74 / 7 = 10.57 (rounded to two decimal places)
Mean with 11:
65 + 11 = 76
76 / 7 = 10.86 (rounded to two decimal places)
Based on the calculations, the values that would increase Jesse's mean number of points are 13, 12, and 11.
