Suppose that the data for analysis includes the attribute age. The age values for the data tuples are (in increasing order)

13, 15, 16, 16, 19, 20, 20, 21, 22, 22, 25, 25, 25, 25,
30, 33, 33, 35, 35, 35, 35, 36, 40, 45, 46, 52, 70.

What is the mean of the data?

Respuesta :

Answer:

Therefore the mean of given data is 29.92.

Step-by-step explanation:

Mean: The actual meaning of mean is the average of data.Mean is ratio of the sum of data to the number of data.

[tex]Mean=\frac{\textrm{sum of data}}{\textrm{total number of data}}[/tex]

Frequency: The number of data is present in the given analysis is known as frequency.

To find out a mean of a data, we have to arrange the data in ascending or descending order.

Here frequency=  27

Given data: 13,15,16,16,19,20,20,21,22,22,25,25,25,25,30,33,33,35,35,35,35,36,40,45,46,52,70

[tex]Mean=\frac{13+15+16+16+19+20+20+21+22+22+25+25+25+25+30+33+33+35+35+35+35+36+40+45+46+52+70}{27}[/tex]           [tex]=\frac{809}{27}[/tex]

         = 29.962

        ≈29.92

Therefore the mean of given data is 29.92.
