Suppose a normal distribution has a mean of 16 and a standard deviation of 4. a value of 26 is how many standard deviations away from the mean? a. −2.5 b.−1.5 c.1.5 d.2.5

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0

step-by-step explanation:

m = 2e

m = 2 so 2 = 2e

1 = e
