I am so lost on this statistics question would someone help me figure out how to answer it?
A random variable X is normally distributed with the mean and standard deviation 1.6. What is the proportion of the data values that lies within 1.6 standard deviations from the population mean?
Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion for ±1.6 Z score.
