Also, use the range nule of thumb to find the minimum usual value H-20 and is Use the gren P 20. the maximum usual value n 160, p 0.25 Enter your answer in the answer box and then click Check Answe

Explanation / Answer

n=160

p =0.25

= np = 160*0.25 = 40

variance = np(1-p) = 160*0.25*(1-0.25) = 30

standard deviation = variance = 30 = 1.732

minimum value -2 = 40-2*1.732 = 36.536

maximum value +2 = 40+2*1.732 = 43.464
