Solution:
We are given that 40th percentile is 125 and it means there is 40% of data below 125. 82nd percentile is 158 and it means there are 82% of data below 158. Now, we have to find the percentage of data between 125 and 158.
Therefore, the percentage of observation between 125 and 158 is:
Hence, approximately 42% of observations lie between 125 and 158.
