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 :] Degree Of freedoms is: :) Chapter 7, Section 2, Exercise 033 Find the expected count and the contribution to the chi-square statistic for the (Control, Disagree) cell in the two-way table below.
