Answer 1

Class 1: 75, 80, 84, 79, 92, 86, 88, 86, 86,90
Class 2: 83, 85, 91, 93, 72, 85, 76, 80, 82, 89

Find the mean score sample. Based on the mean, which class generally performed better on the math test?

The mean score for class 1 is ____. The mean score for class 2 ____. Based on the mean, class ____ generally performed better on the math test.

Answer 2

To answer this question, we need the mean scores for both classes. However, the information provided does not include the mean scores for either class.

Answer 3

To find the mean score of each sample, we need to calculate the average of all the scores in each class.

For Class 1:
Mean score = (75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10
Mean score for Class 1 = 876 / 10
Mean score for Class 1 = 87.6

For Class 2:
Mean score = (83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10
Mean score for Class 2 = 846 / 10
Mean score for Class 2 = 84.6

Based on the mean scores, Class 1 generally performed better on the math test as they have a higher mean score of 87.6 compared to Class 2's mean score of 84.6.
