Answer 2

The mean height of the plant is 30.5 cm

• The mid point of range of heights will be 5, 15, 25, 35, 45, 55
• The corresponding frequency will be 1,4,7,2,3,3
• The mean height of the plant can be calculated as follows.
• x =$\frac{((5*1)+(15*4)+(25*7)+(35*2)+(45*3)+(55*3))}{(1+4+7+2+3+3)} \\= \frac{610}{20} = 30.5 cm$
• The average height of the plant is 30.5 cm
