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

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested

^ means raise to the power of

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
