Answer the following using the 5-step hypothesis testing procedure:
A television channel claims that 40% of the population who watch TV patronize their TV channel. After collecting 70 samples, they found that 30 of them watch the said TV channel. Use ɑ=0.01 to test their claim.
Given that the P-value for the hypothesis test is 0.501, what do you conclude? Does it appear that the heights were obtained through measurement or that the subjects reported their heights?
Follow the steps in testing hypothesis to answer the problem:
