Estimate the fraction of defective computer chips

A semiconductor company wants to estimate the fraction of defective computer chips it produces. Suppose that a random sample of 900 chips has 18 defective chips.

a. Find a point estimate of ?.

b. Find a 95% confidence interval for the proportion ? of defective chips

c. Find a one-sided 95% lower confidence interval for the proportion ? of defective chips.

d. How large a sample should be taken in order to be confident with probability 95% that the margin of error to estimate the fraction ? of defective computer chips is 0.025?
