Cloning A random sample of 800 adults was asked the following question: "Do you think current laws concerning the use of cloning for medical research are too strict, too lenient, or about right?" The pollsters also classified the respondents with respect to highest education level attained: high school, 2-year college degree, 4-year degree, or advanced degree. We wish to know if attitudes on cloning are related to education level. (All the conditions are satisfied - don't worry about checking them.)


a. Write appropriate hypotheses.
b. Suppose the expected counts had not been given. Show how to calculate the expected count in the first cell (106.01).
c. How many degrees of freedom?
d. State your complete conclusion in context.

a. H0: People's opinions on cloning are independent of education level.
    HA: There is an association
b. (382/800)(222) = 106.005
c. (4 - 1)(3 - 1) = 6
d. Reject null (P < 0.05); There is strong evidence that opinion varies with education level. It appears that high school grads are more likely to think regulations are too lenient, people with advanced degrees too strict.
