Answer:
A. D = None of the above
B. B = 18
C. A = 15
D. D = None of the above
Step-by-step explanation:
Rearranging the population from the highest to the lowest.
10, 10, 12, 15, 15, 15, 15, 17, 17, 18, 18, 20, 22, 22, 24, 25, 31, 32, 34, 37
Mean = (summation of all the 20 samples)/ no of samples
Mean per year per 1000 population = 409/20
= 20.45
Median = the middle value (for odd numbered samples)
= the sum of the middle value ÷ 2 ( for even numbered samples)
Median birth per year per 1000 population = (18 + 18)/2
= 18
Mode = the sample that has the number of frequency
Mode per year per 1000 population = 15 (frequency = 4)
Range = highest value sample - lowest value sample
Range per year per 1000 population = 37 - 10
= 27
