Use the contingency table to the right to complete parts (a) through (c) below Total 60 10 70 B 10 20 30 Total 70 30 100 o a. Find the expected frequency for each cell A B Total 1 49 21 70 2 21 9 30 Total 70 30 100 (Type integers or decimals.) b. Compare the observed and expected frequencies for each cell Choose the correct answer below. The expected values are always greater than the observed values. The totals for the observed values are always greater than the totals for the expected values The observed values are always greater than the expected values v The totals for the observed and expected frequencies are the same c. Compute xTAT Is it significant at a=0.107 c. Compute xTAT' Is it significant at a=0.10? First let m; be the proportion of all events of interest in A, and let m; be the proportion of all events of interest in B. Determine the hypotheses. Choose the correct answer below Hp: mq #1y v Ho my =7, Hiimg=my Hyimg#mp Hpimqyzmy Hp my=ms Hyimq
