Normal Distribution Instructions: Assume that the distribution for the following scenario is normal.
Use the standard normal table to find the probability. Round z-scores to the
nearest hundredth. Do not round the probability from the table.
Heights of 2 year old boys are normally distributed with mean 28 inches and
standard deviation of 2.4.
What is the chance a 2 year old boy is less than 26 inches tall? P(2
26) = P(2
What is the chance a 2 year old boy is more than 20 inches tall? P(x
20) = P(Z >=
