The number of cars sold at a dealership over several weeks is given below. 14, 23, 31, 29, 33 what is the standard deviation for this set of population data?

Hence, standard deviation is: 6.87

Step-by-step explanation:

We are given the data as:

14    23    31    29   33

The mean of the data is calculated as the ratio of the sum of all the data points divided by the total number of data points.

Hence,

Now we find the difference between mean and each data entry.

14-26     23-26      31-26      29-26       33-26

-12        -3         5         3          7

Now squaring these numbers to get:

144      9        25         9         49

Now, finding the mean we get the variance(V) as:

Now, standard deviation is defined as the square root of the variance.

Hence standard deviation is:

Hence, standard deviation is: 6.87

answer: i guess 5 units?
