Question
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 woas does the herbal extract result in significant BGL reduction
compared to placebo. Based on HO: Pherbal- Hplacebo20 at sig. level of 0.1, the null
hypothesis states that
95% of all possible differences are less than 2.2
O 90% of all possible differences are less than 11.8
O 90% of all possible differences are less than 4.7
O 90% of all possible differences are higher than -2.2
O 90% of all possible differences are less than 2.2
O 90% of all possible differences are higher than -5.7
O 95% of all possible differences are higher than -4.7
O 90% of all possible differences are higher than 4.7
