Answer 1

Answer:

mean=50

mode=46.6

Step-by-step explanation:

$mean = \frac{summation \: fixi}{summation \: fi} \\ = \frac{6000}{120} \\ mean = 50 \\ modal \: class \\ f0 = 28 \\ f1 = 32 \\ f2 = 24 \\ h = 20 \\ l = 40 \\ mode = l + ( \frac{f1 -f0 }{2f1 - f0 - f1} ) \times h \\ = 40 + ( \frac{32 - 28}{2(32) - 28 - 24} ) \times 20 \\ = 40 + ( \frac{4}{64 - 52} ) \times 20 \\ = 40 + \frac{4}{12} \times 20 \\ = 40 + \frac{20}{3} \\ = 40 + 6.6 \\ mode = 46.6$
