Find the expected count and the contribution to the chi-square statistic for the (Group 1, Yes) cell in the two-way table below.

	Yes	No
Group 1	705	259
Group 2	1170	323

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 count = Enter your answer; Expected count contribution to the chi-square statistic = Enter your answer; contribution to the chi-square statistic Consider the data with analysis shown in the following computer output:

Level	N	Mean	StDev
A	4	10.200	2.684
B	5	16.800	2.168
C	6	10.800	2.387

What is the pooled standard deviation? What degrees of freedom are used in doing inferences for these means and differences in means? Round your answer for the pooled standard deviation to two decimal places. The pooled standard deviation is Enter your answer; The pooled standard deviation . degrees of freedom = Enter your answer; degrees of freedom
