According to a newspaper, 58% of high school seniors have a driver's license. Suppose we take a random sample of 200 high school seniors and find the proportion who have adriver's license. a. What value should we expect for our sample proportion? b. What is the standard error? c. Use your answers to parts (a) and (b) to complete this sentence: We expect ____% to have their driver's license, give or take _____%. d. Suppose we increased the sample size from 200 to 800. What effect would this have on the standard error? Recalculate the standard error to see if your prediction was correct.
