Question

The average weight of a chicken egg is 57 grams with a standard deviation of 5.1 grams. What is the average weight and standard deviation of a carton of a dozen eggs?

Answer 1

hello

to solve this question, we need to know that 1 dozen contains 12 eggs

so, we can simply multiply our values by 12

average weight of a dozen eggs

`\text{weight}=57*12=684g`

standard deviation of a dozen eggs

`S\mathrm{}D=5.1*12=61.2g`

from the calculations above, the average weight of a dozen eggs is equal to 684g and the standard deviation of a dozen eggs is equal to 61.2g
