For one- or two-semester business statistics courses. I am in a statistics class that requires that we use Excel. In other words, there is a significant difference between the heights of the sample, compared with the national average. If my alpha level was set at 0.05, then since the p-value is below the alpha level, I will reject the null hypothesis and accept the alternative hypothesis. Based on the sample data, what should you conclude about the null hypothesis Test using 0.05. So, the p-value for my example is 0.0026. If I hypothesized the sample data will be greater than the national average, then I would select to do a one-tailed analysis instead. Therefore, I will perform a two-tailed analysis. tails – Enter 1 if you want to perform a one-tailed analysis, or a 2 if you want to do a two-tailed analysisįor my example, I did not hypothesize if my sample data was greater or lower than the national average.t – The cell containing the t-statistic.Replace the following components of the function with… In an empty cell, enter the following… =TDIST(t, df, tails) This is achieved by using the TDIST function. The last step is to calculate the p-value by using the t-statistic and the df. Replace cell1 in the equation with the cell containing the first data point and replace cell2 with the cell containing the last data point.īelow is a screenshot of what my example looks like. In Excel, click on an empty cell and enter the following… =AVERAGE(cell1:cell2) This can be easily calculated by using the AVERAGE function in Excel.
