11. The partially filled out contingency table below is for a hypothesis test to see if there is evidence that M and N are not independent. Fill out the missing parts of the table. The expected values go in the parentheses and observed values go above the parentheses. Also put in the missing row totals and column totals. You should be able to complete the table using only addition and subtraction. Do not do the hypothesis test. N 28 )...

Performing a Chi-Square Independence Test The contingency table shows the results of a random sample of 2200 adults classified by their favorite way to eat ice cream and gender. The expected frequencies are displayed in parentheses. At a = 0.01, can you conclude that the adults' favorite ways to eat ice cream are related to gender?
