8. Sketch the areas under the standard normal curve over the indicated intervals, and find the specified areas. Note: z values can be less than zero (negative) but p values are probabilities so they must always be between 0 and 1 because p values are probabilities. a. To the left of z = 1.27 P= b. To the right of z = -1.63 P = c. Between z = -2.48 and z = 0.95 p =
