Answer:
The second data set.
Step-by-step explanation:
In Data set 1, mean is 4.8, the mode is 4.
In Data set 2, the mean is 5 and the mode is 5.
In Data set 3, the mean is 4.6 and the mode is 3.
Mean = (89 + 90 + 87 + 95 + 86 + 81 + 102 + 105 + 83 + 88 + 91 + 79)/12 = 1,076/12 = 89.67
a.) 95% C.I. = 89.67 + or - 1.96(0.23) = 89.67 + or - 0.4508 = 89.22 to 90.12
b.) 99% C. I = 89.67 + or - 2.575(0.23) = 89.67 + or - 0.5923 = 89.08 to 90.26
First, you must use ADDITION to find -12 + 8 (-4)
Then, use MULTIPLICATION to find -4*2 (16
1) Addition
2) Multiplication
The answer is 7.5
But u need 8 tables because you cant cut a table in half. The number facts that i used was 60 divided by 8.
