The SAT is an exam used by colleges and universities to evaluate undergraduate applications. The test scores are normally distributed. In a recent year, the mean test score was 1498 and the standard deviation was 316. (a) What is the probability that a randomly selected test score is less than 16007 Round to the nearest percent. (b) What is the probability that a randomly selected test score is at least 12407 Round to the nearest thousandth. (c) What is the probability that a randomly selected test score is between 1000 and 20007 Round to the nearest hundredth. (d) What is the cutoff score for top 8% of the scores? Round to the nearest tens.
