The standard deviation of any normal random variable is always equal to one.*2 pointsFALSETRUE

A standard normal distribution has a mean of ____ and a standard deviation of ____: 0, 1 depends on sample size 1, 0 depends on the shape of the original distribution

. Standard deviation is a measure of the ________.center of a data setposition of a data value in a data setarea under a normal curvespread of a distribution

If the standard deviation of a set of observations is 0, you can conclude:

Consider the random variable X ∼ N (5, 9); that is, a normal random variable with mean µ = 5and standard deviation σ = 3.(a) Evaluate the following:P(X ≤ 2), P(X > 2), P(X ≤ 8), P(X > 8).(b) Find the points x such that:P(X ≤ x) = 0.10, P(X ≤ x) = 0.25, P(X ≤ x) = 0.52, P(X ≤ x) = 0.99.Page 2 Page 2 of 3

The standard deviation is computed by dividing the sum of the squared deviations by the number of observations. A. TRUE B. FALSE C. I don't know
