95
71
42
16
7
Determine the mean of the data.

Answer 1

Answer:

39.87

Step-by-step explanation:

Find the total number of deaths:

Total = 2 + 12 + 55 + 95 + 71 + 42 + 16 + 7

Total = 300

Find the sum of the age of the 300 deaths:

Sum =2(5) + 12(15) + 55(25) + 95(35) + 71(45) + 42(55) + 16(65) + 7(75)

Sum = 11960

Find the mean:

Mean = Sum/Number of death

Mean = 11960/300 = 39.87

Answer: The mean is 39.87
