The value of minimum usual value is,
The value of maximum usual value is,
Given the values of the parameters of Binomial Distribution are,
Total number of trials (n) = 1490
probability of success in one trial is (p) = 2/5
The probability of failure in on trial is given by,
For Binomial distribution we know that,
Mean
and Standard Deviation
Now, calculating the required measurement we get,
The minimum usual value is given by,
Mean -2 Standard Deviation
The maximum usual value is given by,
Mean + 2 Standard Deviation
Hence the minimum and maximum usual values are -119.2 and 1311.2 respectively.
