7.10 Oil-free deep fryer. Researchers at Purdue University are
developing an oil-free deep fryer that will produce fried food
faster, healthier, and safer than hot oil.5 As part of this
development, they ask food experts to compare foods made with
hot oil and their oil-free fryer. Consider the following table
comparing the taste of hash browns. Each hash brown was rated
on a 0 to 100 scale, with 100 being the highest rating. For each
expert, a coin was tossed to see which type of hash brown was
tasted first.
Expert
              1   2   3   4  5
Hot oil: 78 84 62 73 63
Oil free: 75 85 67 75 66
Is there a difference in taste? State the appropriate hypotheses, and
carry out a matched pairs t test using α = 0.05.
