28% of consumers read the ingredients listed on a product's label.

For a sample of 265 consumers, what is the probability that between 64 and 90 of them read the ingredients listed on a product's label?

The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.

Step-by-step explanation:

We know the proportion of the population, that is π=0.28.

The standard deviation for this sampling distribution is

The value 64 represents a proportion of p=64/256=0.25, and the value 90 represents p=90/256=0.35.

With these values, we can calculate the z-values.

The probability that between 64 and 90 read the ingredients is:

The probability that between 64 and 90 of them read the ingredients listed on a product's label is 0.82.
