  on your experiment the most important result is the p-value, highlighted at left in the pink cell. Since you set your alpha value at 0.05, if the p-value is less than 0.05, you can say that there is a statistically significant difference between the means of your two trials. Note that in this example, p = 2.6 x 10-16, which is < 0.05, so the

  Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.

You can also see the p-value (in red box) indicating whether or not the test is statistically significant (i.e. if p < 0.05). In this example, the p-value is 0.00018. Create your regression curve by making a scatter plot.
