Also, use the range of thumb to tnd the minimum usual value w 20 and the maximum usual value 20 n 1530, p 1/5 Enter your answer in the answer box and then chok Check Answer

Explanation / Answer

ans=

n=1530

p= 1/5

the mean would be: (1530)(1/5) = 306

the standard deviation would be: sqrt (mean)(1-1/5) = 0.8

Next, we find the minimum and maximum usual values according to the equations you gave:

minimum: mean - 2(standard deviation)

= 306 - 2(0.8)

= 304.4

maximum: mean + 2(standard deviation)

= 306 + 2(0.8)

= 307.6
