Cloning a Random Sample of 800 Adults Was Asked the Following

question 26

Essay

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.)
$\begin{array}{|c|c|c|c|c|}\hline & \text { Strict } & \text { Lenient } & \text { Right } & \text { Total } \\\hline \text { High school } & 93 & 107 & 182 & 382 \\& 106.01 & 87.38 & 188.61 & \\\hline \text { 2-year } & \begin{array}{c}27 \\28.31\end{array} & \begin{array}{c}19 \\23.33\end{array}& \begin{array}{c}56 \\50.36\end{array}&102 \\\hline \text { year } & \begin{array}{c}82 \\75.48\end{array} & \begin{array}{c}7 \\62.22\end{array} & \begin{array}{c}140\\134.30\end{array}&44 \\\hline \text { Adv. degree } & 20 & 7 & 17 & 44 \\& 12.21 & 10.07 & 21.73 & \\\hline \text { Total } & 222 & 183 & 395 & 800 \\\hline\end{array}$
$\chi^{2}=\begin{array}{l}1.60+4.40+0.23+ \\0.06+0.80+0.63+ \\0.56+2.40+0.24+ \\4.97+0.93+1.03=17.86\\&p=0.0066\end{array}$
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.
