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 was does the herbal extract result in significant BGL reduction compared to
placebo. Based on HO: Pherbalr Hplacebo=0 at sig. level of 0.1, the null hypothesis states
that
95% of all possible differences are higher than -4.7
O 90% of all possible differences are higher than -2.2
O 90% of all possible differences are less than 11.8
O 95% of all possible differences are less than 2.2
90% of all possible differences are less than 2.2
90% of all possible differences are higher than -5.7
O 90% of all possible differences are higher than 4.7
90% of all possible differences are less than 4.7
