WebTerms in this set (25) Assume that the random variable X is normally distributed, with mean u=100 and standard deviation o=15 Compute the probability P (X > 112). 0.2119. … WebSolution: This problem reverses the logic of our approach slightly. We want to find the speed value x for which the probability that the projectile is less than x is 95%--that is, we want to find x such that P(X ≤ x) = 0.95.To do this, we can do a reverse lookup in the table--search through the probabilities and find the standardized x value that corresponds to 0.95.
WebP(x > 20) = 0.4029, but P(x ¯ x ¯ > 20) = 0.7919 The probabilities are not equal because we use different distributions to calculate the probability for individuals and for means. When asked to find the probability of an individual value, use the stated distribution of its random variable; do not use the clt.
