When using the beta distribution, the denominator of the formula for standard deviation should be adjusted by converting the range into the correct z-score value. Thus, option C is correct.
The beta distribution is a group of uninterrupted probability density functions with two significant groups of identification. Its only valid range is between 0 and 1.
To adjust the denominator of the mean of the supplied range when using the beta distribution, the spectrum must be translated into the proper significance level.
It concerns the calculation of the mean and the value that results from the subsequent. Therefore, option C is the correct option.
