Question

2
marshawn sells eggs at the farmers market that is near her chicken farm. since her farm is at the end of a long, uneven road, the ride to the farmers market can be rather bumpy. so, she wants to design a crate with cushioning that prevents the eggs from cracking as she transports them to the farmers market.
before she builds large crates for the eggs, she tests four smaller crates with cushioning made out of different materials. all of the smaller crates are divided into six sections that each hold one egg. she tests her crate models by driving to the farmers market three different times. the data for each type of cushioning is shown in the table below.

type of cushioning	number of eggs cracked
cardboard	3	5	4	4.0
foam	2	1	1	1.3
plastic	4	4	6	4.7
cotton	1	3	2	2.0

based on the data, which of the following describes the best way to modify the egg crate model for further testing?
a. use thinner cotton
b. use thicker plastic
c. use thicker foam
d. use thinner cardboard

Explanation:

To determine the best modification, we analyze the average number of cracked eggs for each cushioning material. Foam has the lowest average (1.3), meaning it's the most effective at preventing cracks. So, improving the foam - based cushioning (like using thicker foam to potentially enhance its effectiveness) is the best approach for further testing. Options A, B, and D involve materials with higher average cracked eggs or modifications that would likely reduce effectiveness.

Answer:

C. use thicker foam
