28. Maresha took a random sample from a package of jelly beans without looking and found that \( 30 \% \) of the beans were red. Suppose there are 250 jelly beans it the package. How many can she expect to be red? 7. SP. 2

If Maresha found that \( 30\% \) of the jelly beans in her sample were red, we can calculate the expected number of red jelly beans in a package of 250 by multiplying the total number of jelly beans by the percentage of red beans. So, \( 250 \times 0.30 = 75 \). Therefore, Maresha can expect to find approximately 75 red jelly beans in the package! Now, keep in mind that sometimes small samples might not perfectly represent the entire population. It’s always fun to experiment with another sample and see if the proportion holds!
