Figur for failing within 1, 2, and 3 of the mean in a normal distribution. deviations IQ scores for the general adult population form a nearly normal distribution, with mean 100 pts and standard deviation 15 pts. Verify that the 68% - 95% -99.7% rule works for this distribution. The distribution is graphed below and each box represents 1% of the data. + 60 70 80 90 100 110 120 130 140 Using the 68%-95% -99.7% rule, find each of the following probabilities a) P(x> 130 pts) = P(a randomly selected person scores 130 pts or higher) i) [Insert your answer here] b) P(x > 70 pts) i) [Insert your answer here] c) P(a person is more than 15 points different from the average, in either direction) d) P(85
