The average SAT score is 1069 with a standard deviation of 190. The distribution of all SAT scores is known to be normally distributed. Use the Empirical Rule to address the following questions. Hint: sketch the distribution to help visualize the problem. Approximately 99.7% of the test scores lie between 499 and 1639 If 690,000 students took the SAT, approximately how many students scored between 689 and 14497 655500 If 690,000 students took the SAT, approximately how many students scored between 879 and 1259? hp
