Set significance level and find associated critical value. Note, this is a one-sided test (finding whether the coefficient is above or below 0) so the Excel command used is “=T.INV.2T(0.02,397)” at the 1% significance level. “0.02” is used in the excel command because the in this case is not being used for a 2-sided test

A test statistic is calculated. A common test statistic is a t-value. In this case, we are testing the value of one population mean, and the t-value (or sometimes used - a z value) is a measure of “how far” the sample mean is from the population mean that is specified in the null hypothesis.

In B46 use the AVERAGE function to calculate the sample mean for B10:B39. In B47 calculate the test statistic, z, using the formula: z = (sample mean – hypothesized mean) / (0.8/ sqrt of sample size). Enter = (B46-100) / (0.8/SQRT(B45)) In B48 use the NORMSDIST function to calculate the 1-side P Value. Enter = NORMSDIST(B47).
