Question

Here are the math test scores of 10 randomly selected students from class one and class two class. One has 75, 80, 84, 79, 92, 86, 88, 86, 86, and 90 class two is 83, 85, 91, 93, 72, 85, 76, 80, 82, and 89 find a mean score of each sample based on the mean which class generally performed better on the math test the main score for a class one is what is the answer? The score for class is what is the answer based on the mean class blank generally performed better on the math test please help with this question.

Answer 1

To find the mean score of each sample, we need to add up all the scores and then divide by the total number of scores.

For class one:
(75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 856 / 10 = 85.6

For class two:
(83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 846 / 10 = 84.6

Therefore, the mean score for class one is 85.6 and the mean score for class two is 84.6.

Based on the mean score, class one generally performed better on the math test.

So the answer is:
- The main score for class one is 85.6
- The main score for class two is 84.6
- Based on the mean, class one generally performed better on the math test.
