It can be shown that μx = 7/12 and σ2x = 11/144. What is the probability that the value of x is more than 1 standard deviation from the mean value? (Round the answer to four decimal places.) P (x is more than one standard deviation from the mean value) =

Respuesta :

Answer:

Step-by-step explanation:

Here the the value of Z should be greater than 1 .

P [( X - μ)  / σ ) > 1

from the chart , for value of z greater than 1 , the probability is

1 - .8413 = .1587 .

So the required probability is .1587 .
