Question

A television manufacturer had claimed in its warranty that in the past less than 10 % of its television sets needed any repair during their first five years of operation. In order to test the validity of the claim, a government testing agency selects a sample of television sets did a hypothesis test. If we assume that p-value is 0.4 (this is not the p-value in other questions with this case), can we conclude that the manufacturer's claim is valid at 10 level of significance? a) No b) Yes c) Do not know

Explanation / Answer

Since p value > 0.10 level, we do not have sufficient evidence to support the claim.

So we cannot conclude that manufacturer's claim is valid at o.10 level of significance.

Option a) is correct. (We consider given p value in question for conclusion).
