Question

A health journal conducted a study to see if packaging a healthy food product like junk food would influence children's desire to consume the product. A fictitious brand of a healthy food product sliced apples was packaged to appeal to children. The researchers showed the packaging to a sample of 371 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=3.54 and s- 2.56. Suppose the researchers knew that the mean willingness to eat an actual brand of sliced apples (which is not packaged for children) is 3. Complete parts a and b below. a. Conduct a test to determine whether the true mean willingness to eat the brand of sliced apples packaged for children exceeded 3 . Use α= 0.10 to make your conclusion. State the nul and alternative hypotheses. Ha: H> 3 Find the test statistic. (Round to two decimal places as needed.)

Find z statistic and p-value based on the info above. Thanks!

Answer 1

3.54-3 2 56 0

Conclusion :- p-value is less than alpha = 0.10 then conclude that the reject the null hypothesis (H0).
