Syntax. CONFIDENCE.T(alpha,standard_dev,size)
Definition. This function returns the confidence interval for the expected value of a random variable by using a Student’s t-test.
Arguments
alpha (required). The probability of error used to calculate the confidence interval. The confidence interval equals 100*(1 – alpha)%, which means that an alpha of 0.05 indicates a 95-percent confidence level.
standard_dev (required). The standard deviation of the population. The argument standard_dev is assumed to be known.
size (required). The size of the sample.
