<PRE><B>Question 1022177</B>
We need to calculate the z-value in order to find the probability
:
z-value = (25 - 25) / 5 = 0
:
consult table of z-values
P(Y &lt; 25) = 0.5000 or 50%
:
this tells us that 50% of the values in a normal distribution will be below 25 and 50% of the values will be greater than 25
:
strictly speaking we do not include the = when using a normal distribution, = is reserved for the binomial probability distribution
