The thorax lengths in a population of male fruit flies follow a normal distribution with mean 0.785 millimeters (mm) and standard deviation 0.07 mm. what are the median and the first and third quartiles of thorax length?

In this exercise we have to use the knowledge of distribution to calculate the value of the first and third quartiles, in this way we can say that:

We can estimate the expected value of the various percentiles assuming the normal distribution, so we have to make the conversion as:

The quartiles, 25th and 75th percentile, happen about 2/3 of a predictable difference external the mean. In other words ±.67 standard departure exist 50% of the likelihood of something happening:
