WebIt is compared to a t with (n-k) degrees of freedom where here n = 5 and k = 3. Column "P-value" gives the p-value for test of H0: β j = 0 against Ha: β j ≠ 0.. This equals the Pr{ t > t-Stat}where t is a t-distributed random variable with n-k degrees of freedom and t-Stat is the computed value of the t-statistic given in the previous column. WebX-bar is the sample mean. μ is the population mean. S is the sample standard deviation. n is the number of units in the sample. Example: If the population mean is 6 and the sample mean is 8, calculate the t-statistic if the standard deviation is 4 and the number of units in the sample is 16.

WebX and X̅ are standardised slightly differently. In both cases, the denominator is the square root of the variance, like so: For X, Z = (X-μ) / σ.
