The average number of employees that call in sick for the day over the course of a year is 25.

The number of employees that call in sick on 12 days are

25, 10, 16, 39, 27, 25, 32, 25, 25, 22, 28, and 14.

Enter the sample mean and the population mean.

x¯=
employees

μ=
employees

Step-by-step explanation:

The mean of a set of numbers is the sum divided by the number of terms.

x¯= 25+10+16+39+27+25+32+25+25+22+28+14

                                   11

x¯ = 261.27

            11

x¯= 23.75 18

x¯= 23.75 18

The mean should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.

x¯=23.8

25,10,16,39.27,25,32,25,25,22,28,14

Set up the formula for sample standard deviation. The standard deviation of a set of values is a measure of the spread of its values.

s=  n^∑  i=1    √(xi−xavg)²

                            N-1

Set up the formula for standard deviation for this set of numbers.

s= ⎷(25−23.8)²+(10−23.8)²+(16−23.8)²+(39.27−23.8)²+(25−23.8)²+(32−23.8)²+(25−23.8)²+(25−23.8)²+(22−23.8)²+(28−23.8)²+(14−23.8)²

                                       11−1

s= √68.05209

The standard deviation should be rounded to one more decimal place than the original data. If the original data were mixed, round to one decimal place more than the least precise.
