If you assume the samples are representative how many whole wheat bagels might you infer are sold at each store

Alexxandr [17]

Maurine owns three bagel shops. Each shop sells 500 bagels per day. Maureen asks her store managers to use a random sample to see how many whole wheat bagels are sold at each store each day. Shop A has total of 50 bagels in sample and 10 are whole wheat bagels. Store B has a total of 100 bagels in sample and 23 are whole wheat bagels. Shop C has 25 total bagels in sample and 7 are whole wheat bagels.

We find fraction of whole wheat bagels to the sample for each shop using given information

Shop A = $\frac{10}{50} = 0.20$
