Respuesta :

The four heaviest eggs are 2 ounces, 2 ounces, 2 1/4 ounce is, and 2 1/2 ounces. Add these together to total 8 3/4 ounces.

The four heaviest eggs have a sum of 8 3/4 ounces.

The total weights of the harvest eggs is 19 1/4 ounces

How to determine the total weight?

From the line plot, we have the following frequency distribution

1 1/2 ==> 2

1 3/4 ==> 4

2     ==> 2

2 3/4 ==> 1

2 1/2 ==> 1

The total weight is the product of the weights and the frequencies.

So, we have:

Total = 1 1/2 * 2 + 1 3/4 * 4 + 2 * 2  + 2 3/4 * 1 + 2 1/2 * 1

Evaluate the sum

Total = 19 1/4

Hence, the total weights of the harvest eggs is 19 1/4 ounces
