Question

2. Confirm that the mean for Group A is 6.76 ounces, and calculate the mean for Group B.

Answer 1

Mean of weights for Group A = 6.76

Mean of weights for Group B =6.48

Missing Portion:

The 10 tomatoes with their weights shown. They have been ordered from largest to smallest based on weight.

1. 9.1
2. 8.4
3. 8.0
4. 7.7
5. 7.3
6. 6.4
7. 5.9
8. 5.2
9. 4.4
10. 3.8

Imagine that someone assisting you uses a random-number generator or some other impartial selection device and randomly selects Tomatoes number 1, 4, 5, 7, and 10 to be in Group A.

Explanation:

So, by default, Tomatoes number 2, 3, 6, 8, and 9 will be in Group B.

Weights of tomatoes in group Group A :

9.1 , 7.7, 7.3 , 5.9, 3.8

Weights of tomatoes in group Group B :

8.4, 8, 6.4, 5.2, 4.4

Mean of weights for Group A =
`(9.1+7.7+7.3+5.9+3.8)/(5)` = 6.76 ounces

Mean of weights for Group B =
`(8.4+8+6.4+5.2+4.4)/(5)` = 6.48 ounces

Which confirms mean for group A is 6.76 ounces and gives us mean of Group B as 6.48 ounces
