CONFIDENCE.T Function Explained
The CONFIDENCE.T
Function in Microsoft Excel calculates the confidence interval
for a population mean, using a Student's t-distribution
. It takes three arguments: alpha
, standard_dev
, and size
. Alpha
is the significance level used to compute the confidence level, standard_dev
is the population standard deviation, and size
is the sample size. The function returns the confidence interval for a population mean.

- alpha: The significance level used to compute the confidence level. It must be a number between 0 and 1.
- standard_dev: The population standard deviation for the data range and is assumed to be known.
- size: The sample size.
