Sometimes the researcher wants to test whether the treatment mean is greater than/equal to or less than a reference value. For example, I want to know if the average productivity of my treatment is higher than the average productivity of a given country. For this, this function allows comparing the means with a reference value using the t test.
plot_tonetest(tonetest, alpha = 0.95)
returns a density plot and a column plot to compare a reference value with other treatments.
