A fictitious brand of a healthy food productlong dashsliced appleslong dashwas packaged to appeal to children. The researchers showed the packaging to a sample of 330 school children and asked each whether he or she was willing to eat the product. Willingness to eat was measured on a 5-point scale, with 1="not willing at all" and 5="very willing." The data are summarized as x = 3.27 and s=2.27. Suppose the researchers knew that the mean willingness to eat an actual brand of sliced apples (which is not packaged for children) is u=3. Complete parts a and b below.
Conduct a test to determine whether the true mean willingness to eat the brand of sliced apples packaged for children exceeded 3. Use α=0.01 to make your conclusion.
