Question

Find the expected count and the contribution to the chi-square statistic for the left-parenthesis B comma F right-parenthesis cell in the two-way table below. Upper D Upper E Upper F Upper G Total Upper A 39 32 39 34 144 Upper B 75 91 66 59 291 Upper C 21 36 29 31 117 Total 135 159 134 124 552 Round your answer for the excepted count to one decimal place, and your answer for the contribution to the chi-square statistic to three decimal places. Expected countequals contribution to the chi-square statisticequals

Explanation / Answer

The Table is as follows

The Expected value = Column Total * Row Total/N

For (B,F) Expected value = 134 * 291/552 = 70.6

Contribution to the chi square statistic = (O-E)2/E = (66-70.6)2/70.6 = 0.299 (Which can be approximated to 0.300)

D E F G Total A 39 32 39 34 144 B 75 91 66 59 291 C 21 36 29 31 117 Total 135 159 134 124 552
