Which is an example of a null hypothesis appropriate for a chi-squared goodness of fit test, using our competition lab with the forks, knives and spoons? Question 14Answer a. The observed values do not differ from the expected values (for example, the energy units ratio of foam, strings, blocks, and straws taken did not differ from 1:1:1:1) b. Energy units of foam taken differed from energy units of strings, blocks, and straws taken c. The observed values differ from the expected values (for example, there are more energy units taken of foam than taken of strings, blocks, or straws) d. A more specific version of b: eg. energy units of foam are taken in preference to energy units of string (or other energy units, depending on species of utensil)
