A herbal extract is claimed to lower the blood glucose level. 10 prediabetic subjects were give capsules containing lactose for 1 month. Another sample of 10 subjects were given capsules containing dried herbal extract for one month. Assuming the samples were taken from populations of known equal standard deviations of 10 and the question of interest was does the herbal extract result in significant BGL reduction compared to placebo. Based on HO: Hherbal Hplacebo20 at sig. level of 0.1, the null hypothesis states that 90% of all possible differences are less than 4.7 95% of all possible differences are higher than -4.7 90% of all possible differences are less than 11.8 95% of all possible differences are less than 2.2 90% of all possible differences are higher than -2.2 90% of all possible differences are less than 2.2 90% of all possible differences are higher than -5.7 90% of all possible differences are higher than 4.7

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
