Question

Find the average of the ff: 1. 10, 12, 16, 17,20 2. 0, 3,6,9

Answer 1

Answer:

1) 15

2) 4.5

Step-by-step explanation:

1 ) 10, 12, 16, 17,20

Average = $\frac{\text{Sum of all observations}}{\text{Total no. of observations}}$

Average = $\frac{10+12+16+17+20}{5}$

Average = $15$

2) 0, 3,6,9

Average = $\frac{\text{Sum of all observations}}{\text{Total no. of observations}}$

Average = $\frac{0+3+6+9}{4}$

Average = $4.5$
