StDev is the standard deviation for the total population.

Size is the size of the total population.

### Shembull

## CONFIDENCE.NORM

Returns the (1-alpha) confidence interval for a normal distribution.

### Sintaksa

CONFIDENCE.NORM(Alpha; StDev; Size)

Alpha is the level of the confidence interval.

StDev is the standard deviation for the total population.

Size is the size of the total population.

### Shembull
