Open StatCrunch. Use the Stat > Calculators > Normal command to open the normal calculator. For this first problem, leave the mean as 0 and the standard deviation as 1. This implies we are working on the standard normal curve. Fill in the last row so that it reads: "P(X 1.5)" and leave the right side of the equal side empty. The press compute to find the probability that a value is less than or equal to 1.5 on the standard normal curve. Answer: (Round to FOUR decimal places.) Now find the probability that a value is GREATER than or equal to 0.8. That is, find P ( X 0.8 ) . Be sure to change the inequality sympol in the last row. Answer: (Round to FOUR decimal places.)
