If a random sample of 100 teen drivers is taken, the standard error for the sampling distribution of the sample proportion is 0.0488. The sampling distribution will be approximately normal. There is a 0.1587 probability that the sample proportion is less than 0.80. There is a 0.9500 probability that the sample proportion is within 0.02 of the population proportion of 0.82.
