A random sample of 50 lumbar supports used by go-cart racers were subjected to a crash test, andtear was observed on 18 of these lumbar supports. Using the point estimate of p from the 50 supports,how many lumbar supports must be tested to be 95% confident that the error in estimating p is lessthan 0.02?a. 2213b.
