Blend Taste-Testers

Solution

a) The experiment is getting the blend which people like out of 4.

100 times done.

b) Prior to conducting we can assume that four blends are equal and check it with proper test.

Equal prob assigned to all 4 and chi square test can be done.

c) When equal prob we must assign experimental outcomes as 25 each.

df = 3

p value = 0.999 at 95%

Hence accept null hypothesis.
