Question
An independent survey claimed that the average number of people who will vote for BBM in Visayas is greater than the average number of people who will vote for VPLR in Luzon. To validate this survey, a group of researchers conducted a post-test.
In a survey of 210 people in Luzon, the average number of people who will vote for VPLR is 153 with a population standard deviation of 7.6. In a survey of 200 people in Visayas, the average number of people who will vote for BBM is 155 with a population standard deviation of 12.6. At α = 0.05, can people trust the result of the survey?
