Lynn asked six friends how many cars their parents own. she recorded 1, 1, 2, 2, 2, and 4 cars.

what is the mean absolute deviation of the number of cars? round to the nearest tenth, if needed.

a. 0.7 cars
b. 1.1 cars
c. 1.4 cars
d. 2 cars

Option: A is correct.

0.7 cars.

Step-by-step explanation:

Lynn asked six friends how many cars their parents own. She recorded 1, 1, 2, 2, 2, and 4 cars.

The data is already in the increasing order as:

1     1      2       2       2    4

There are total 6 entries.

Also mean of the data is given by:

now we find the absolute value between the data points and mean as follows:

|1-2|=1

|1-2|=1

|2-2|=0

|2-2|=0

|2-2|=0

|4-2|=2

Now, we find the mean of the following absolute value as:

which is approximately equal to 0.7

Hence,  the mean absolute deviation of the number of cars is 0.7 cars.
