Brad Davenport a consumer reporter for the national cable TV channels, is working on the story determining the generic food products and comparing them to their brand-name counterpart. According to the Brad, consumers claim to like the brand-name products better than the generics, but they can't even tell which is which. To test this theory, Brad gives each of 200 customers two potato chips 1 generic, the other a brand-name and ask them which one is the brand-name chip. Notice that if a person cannot tell the difference, they would have a 50-50 chance of identifying the brand-name chip. One hundred and ten of the subjects correctly identified the brand name chip.
A) What is the appropriate null and alternative hypothesis to disprove Brad's claim that people can't distinguish between generic and brand-name chips?
B) Test the hypothesis using alpha equals 0.025.
C) Calculate the p value for the hypothesis test.
D) Is the curve shaded in the left, right or double sided tail?
