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'm sorry, but that is not correct.
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.
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.
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 :)
