Question Here are the math test scores of 10 randomly selected students from Class 1 and Class 2. 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 of each sample. Based on the mean, which class generally performed better on the math test? (2 points) The mean score for Class 1 is . The mean score for Class 2 is . Based on the mean, Class generally performed better on the math test.

Answer 1

The mean score for Class 1 is (75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 84.6

The mean score for Class 2 is (83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 83.6

Therefore, Class 1 generally performed better on the math test with a slightly higher mean score of 84.6 compared to Class 2's mean score of 83.6.

Answer 2

Based on the mean, Class generally performed better on the math test.

Answer 3

Apologies for the error in my previous response. According to the mean scores calculated:

- Mean score for Class 1: 84.6
- Mean score for Class 2: 83.6

Therefore, based on the mean scores, Class 1 generally performed better on the math test with a higher mean score of 84.6 compared to Class 2's mean score of 83.6. Thank you for pointing out the mistake.
