Market researchers would like to know if consumers can taste the difference between a product made with low calorie oil and the same product made with regular oil. A random sample of 400 people are blindfolded and given both products to taste. Overall, 230 people correctly guess which is the low calorie product. Is there evidence of a difference in taste between the two products?

a) sample % of correct guesses is 1.50 standard errors above 50%, so there is no evidence of difference in taste.
b)Sample % of correct guesses is 1.75 standard errors above 50% so there is no evidence of difference in taste.
c) sample % of correct guesses is 3 standard errors above 50% so there is evidence of a difference in taste.
