The weekly salaries (in dollars) for
kompoz [17]

Answer:

a) Median stays the same

b) Mean is decreased by $9

Step-by-step explanation:

The median is the number or the average of the two numbers that is in the middle of a sorted distribution of numbers,

Here the median number will be the 5th number counting from left or right from the sorted list of numbers. Therefor is is 891.

When 1027 is changed to 946 it will fall between 938 and 1002. So updated sorted list of numbers will now look like,

679, 715, 799, 844, 891, 917, 938, 946, 1002

Here also median will be the 5th number which will be equal to 891.

Therefore, , median will not change.

Mean is the value we get by taking the total value of the salaries and divide it by the number of employees.

In the initial case,

Mean =\frac{679+715+799+844+891+917+938+1002+1027}{9} =868

When the salary is changed from $1027 to $946,

Mean=\frac{679+715+799+844+891+917+938+1002+946}{9} =859

Therefor we can see that Mean has decreased by $9.
