Which of the following is the main of the set of data below? 30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Marianna [84]

Answer:

The mean of the data is 26.

Step-by-step explanation:

Consider the provided data:

30, 29, 28, 30, 24, 12, 26, 33, 25, 23

Mean can be calculated as:

The average of all the data in a set.

$x=\frac{\Sigma x_{i}}{n}$

Therefore,

$x=\frac{30+29+28+30+24+12+26+33+25+23}{10}$

$x=\frac{260}{10}$

$x=26$

Thus, the mean of the data is 26.
