Question

A researcher conducts a randomized experiment to test whether a diet that includes 100 grams of blueberries each day will improve the function of the cathelicidin antimicrobial peptide gene which is known to have an important role in the immune system. The gene's function is measured in 40 subjects who added 100 grams of blueberries to their daily diet and 40 control subjects who ate similar meals but without the blueberries. At the end of the experiment, a significance test is conducted and the p-value is found to be 0.0042. This says that:

Explanation / Answer

MOSTLY THE SIGNIFICANCE TEST ARE DONE AT 5% = 0.05

AND AS THE P VALUE = 0.0042 WHICH IS VERY SMALL TO 0.05

AND WHEN THE P VALUE IS SMALL TO THE SIGNIFICANCE LEVEL WE REJECT THE NULL HYPOTHESIS

HERE THE NULL HYPOTHESIS WILL BE THAT THE DIET INCLUSING 100 GRAMS OF BLUEBERRIES EACH DAY WILL NOT IMPROVE THE FUNCTION OF CATHELICDIN ANTIMICROBIAL PEPTIDE GENE, HENCE THE NULL HYPOTHESIS WILL BE REJECTED
