Can you explain the step by step solution on chapter 2 , problem 1AYK in the basic practice of statistics 6th edition

Answer 1

Answer #1

Solution:-

The mean of the given data is 30841.

$ar{x}=rac{sum x}{n}$

$616820 0$

$T-30841$

After arranging all the data points in ascending order we can see that only 6 of the 20 pieces have a breaking strength less than the mean.

Hence the distribution of breaking strength is left skewed. The low outliers have also decreased the value of the mean.
