Answers

Answer:

it depends on the work place to play it safe i would choose 12

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

What is sample mean?

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25
