Answer 2

Answer:

mode = 45

mode = 45median = 30

mode = 45median = 30mean = 27

Step-by-step explanation:

interval frequency mid- fm. cf

interval frequency mid- fm. cf point

0-10 6 5 30 6

10-20 7 15 105 13

20-30 2 25 50 15 n/2 = 30/2

30-40 5 35 175 20 n/2 = 15

40-50 10 45 450 30

total 30 - 810 -

Mean = sum of fm

Mean = sum of fm sum of frequency

mean = 810 = 81

30 3

mean = 27

median = L1 + n/2 - cf x common number

median = L1 + n/2 - cf x common number f

median = 20 + 15 - 13 x 10

2

median = 20 + 10

median = 30

mode = maximum time occurs frequency

mode = 40-50 ( 40-50 = 10 times)

mode = 40+50

2

mode = 90 = 45

mode = 90 = 45 2
