Answer:
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.
