Finding probability using normal distribution
WebUsing a table of values for the standard normal distribution, we find that P (–1 < Z ≤ 1) = 2(0.8413) – 1 = 0.6826 Thus, there is a 0.6826 probability that the random variable will take on a value within one standard deviation of … WebTo find areas to who right, we need into remember the complement rule. Take a minute and look back along the rule from Section 5.2. Been we know the entire area is 1, (Area to …
