CONFIDENCE.T
This function returns the confidence interval for a population mean.
Syntax
CONFIDENCE.T(alpha, stdev, size)
Arguments
This function has these arguments:
Argument | Description |
|---|---|
alpha | Alpha, significance level used in calculating confidence level, where the confidence level is 100 times (1-alpha)% |
stdev | Population standard deviation for the range |
size | Number representing the size of the sample; if not an integer, the number is truncated |
Remarks
The function uses a Student's t distribution. If size = 1, the function returns a #DIV/0! error value.
If any argument is non-numeric, the function returns the #VALUE! error value.
Data Types
Accepts numeric data for all arguments. Returns numeric data.
Examples
CONFIDENCE.T(0.5,B4,D5)
CONFIDENCE.T(0.5,R4C2,R5C4)
CONFIDENCE.T(0.05,3.5,150) gives the result 0.5646928012079743
