Answer:
1) 15
2) 4.5
Step-by-step explanation:
1 ) 10, 12, 16, 17,20
Average = [tex]\frac{\text{Sum of all observations}}{\text{Total no. of observations}}[/tex]
Average = [tex]\frac{10+12+16+17+20}{5}[/tex]
Average = [tex]15[/tex]
2) 0, 3,6,9
Average = [tex]\frac{\text{Sum of all observations}}{\text{Total no. of observations}}[/tex]
Average = [tex]\frac{0+3+6+9}{4}[/tex]
Average = [tex]4.5[/tex]
