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?
Fill in the blanks:
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
I'm sorry, but that is not correct.
just use ChatGPT lol if you cant find or confirm the answer.
oh the answers for the practice are (1.) 88.1 (2.) -8 (3.) 38 ( 4.) class 1 is 84.6, class 2 is actually cant find it :( but class 1 has a generally better performance. (5.) pizzashop 1 is 21.5 and pizza shop 2 is 20. overall pizza shop 2 has a faster delivery time :)
The mean score for Class 1 is 84. The mean score for Class 2 is 83. Based on the mean, Class 1 generally performed better on the math test.
I apologize for the error. Let's recalculate the mean scores.
For Class 1:
(75 + 80 + 84 + 79 + 92 + 86 + 88 + 86 + 86 + 90) / 10 = 856 / 10 = 85.6
For Class 2:
(83 + 85 + 91 + 93 + 72 + 85 + 76 + 80 + 82 + 89) / 10 = 846 / 10 = 84.6
Therefore, the mean score for Class 1 is 85.6 and the mean score for Class 2 is 84.6. Based on the mean, Class 1 generally performed better on the math test.
