2. confirm that the mean for group a is 6.76 ounces, and calculate the mean for group b.

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.

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.

Step-by-step 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 = = 6.76 ounces

Mean of weights for Group B = = 6.48 ounces

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

The simplified expression would be 4

Step-by-step explanation:

So since we have parentheses in this expression we have to use the steps of PEMDAS (parentheses, Exponent, Multiplication, Division, Addition, Subtraction)

So the first step is to solve what's in the parentheses

Then we multiply

Since we have simplified the equation so far let's write it out

Now we just solve the equation as written
