•Suppose that someone asks you if the average number ofchildren among families in a large Midwestern city is 4. Youdisagree and believe that this average in less than 4. Test thehypothesis with the following sample data: •n = 195 •Mean # of children = 3.68 •Sx = 1.1 children •What is the critical value of children in terms of raw scoresnecessary to reject the null hypothesis? •Suppose that someone asks you if the average number ofchildren among families in a large Midwestern city is 4.

Explanation / Answer

What is the critical value of children in terms of raw scoresnecessary to reject the null hypothesis? If =0.05, the critical value is Z(0.05)=1.645 (check normaltable.) If =0.01, the critical value is Z(0.01)=2.33 (check normaltable) Hope this helps.
