Problem 4

True or False: A confidence interval for a population standard deviation is of the form point estimate ± margin of error.

Accepted Solution
Step-by-Step Solution:

Step 1 of 5) A confidence interval for a population standard deviation is of the form of point estimate ± margin of error. In Example 4, we were able to see how a change in level of education affected employment status. Therefore, we are treating level of education (the column variable) as the explanatory variable and employment status as the response variable. We could also construct a conditional distribution of level of education by employment status. In this situation, we would be treating employment status (the row variable) as the explanatory variable. The procedure is the same, except the distribution uses the rows instead of the columns. In this case, the explanatory variable is employment status and the response variable is level of education. As is usually the case, a graph can p
