SMALL: greater than 43 grams, less than 50 grams

MEDIUM: greater than 50 grams, less than 57 grams

LARGE: greater than 57 grams, less than 64 grams

EXTRA LARGE: greater than 64 grams, less than 71 grams

JUMBO: greater than 71 grams.

The output of a particular egg farm has a mean weight of 62 grams with a standard deviation of 8 grams. What is the percentage of egg output of this farm in each size category?

Small eggs are between 43-50 grams.

(43-62)/8 ≤ Small eggs ≤ (50-62)/8

Look up these two z scores in table in back of your stat text labeled something like "areas under normal distribution" to find proportion between these two points. Convert to percentage.

Do the same with the other categories.

I hope this helps.
