given that mean number is 34 and standard deviation is 12 fi

given that mean number is 3.4 and standard deviation is 1.2, find the maximum and minimum usual values

Solution

To find maximum and minimum value when mean and standard deviation is given we need to use the formula which is like this:

(mu-2*standard deviation,mu+2*standard deviation)

where mu=mean

so putting values in the above formula we have:

(3.4-2*1.2 , 3.4+2*1.2)

(1 , 5.8) (minimum , maximum) Answer
