The TreeDropp'd Fruit Company wants to sell its apples overseas in attractive pink and yellow gift boxes. To design the boxes, the company needs to estimate the average
diameter of their apples. A random sample of 50 apples has a mean of 4.1 inches. Using
previous research, you assume a population standard deviation o of .4 inches. (As you
continue to study statistics you will look at how to estimate o, which is what researchers
do in the real world. For now, assume you know it.)
E. If you wanted to construct a 99% confidence interval with a margin of error of
1% of the point estimate, what is the minimum number of apples you will need
in your sample?
