<u>Given</u>: The number of woodpeckers in a forest have
a mean = 20 , mode= 20 , and standard deviation = 5
<u>Computation:</u>
The range of data between 2 standard deviations from the mean is given by :-
Mean ± 2 (Standard deviation)
i.e. ( Mean- 2 (Standard deviation), Mean + 2(Standard deviation)
i.e. (20-2(5), 20+2(5))
i.e. (20-10, 20+10)
i.e. (10, 30)
Required range = (10, 30) which contains approx. 95% of the data ( By 68-95-99.7 rule)
