Answer 1

Answer:

3+5+1+(-4)+(-5)+6/2=

3+5+1-4-5+6/2

6/2=3ans

Answer 2

The mean of the given data is 0.86.

• Mean is the most commonly used measure of central tendency.
• It is calculated central value for a given set of observations.
• Given observations are

3, 5, 1, -4, -5, 6, 0

• This is an ungrouped data.
• Mean for ungrouped data is given by

Mean = ( sum of observations)/(number of observations)

• Mean = (3+5+1-4-5+6+0)/7

Mean = 6/7

Mean = 0.86
