Give a simple example of a left-skewed distribution. Choose the correct answer below. A. The number of books read during the school year by fifth graders is a left-skewed distribution. B. The heights of a sample of 55 men is a left-skewed distribution. C. The speed of cars on a road where a visible patrol car is using radar to detect speeders is a left-skewed distribution. D. The weights of a sample of 500 dogs of varying breed is a left-skewed distribution.

Correct option is (C).

Step-by-step explanation:

A left-skewed distribution curve has a longer tail towards the left of the data and most of observation are collected on the right.

The properties of a left-skewed distribution are:

The mean of a data is computed by taking all the values into consideration. Whereas the median is a single value and is computed by using the number of observations.

So if the mean of a data is less than the median it can be interpreted that most values are lesser in magnitude.

The speed of cars on a road where a visible patrol car is using radar to detect speeders is a left-skewed distribution.

This is because people will drive according to the speed limit to avoid getting a ticket.

So most of the speed values will be less and very few will be more than the speed limit.

Thus, the correct option is (C).

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.
