To find the probability
using the standard normal distribution, we can look at the standard normal distribution table (Z-table) for the values corresponding to z-scores.
- The Z-table value for
is approximately 0.5120. - The Z-table value for
(which corresponds to the mean) is 0.5000.
Now calculate the probability:
Thus, the probability
is 0.0120, or 0.0120 when rounded to four decimal places.
