In Comparing Two Population Means of Interval Data, We Must $\mu _ { 1 } - \mu _ { 2 }$

question 43

True/False

In comparing two population means of interval data, we must decide whether the samples are independent (in which case the parameter of interest is $\mu _ { 1 } - \mu _ { 2 }$ ) or matched pairs (in which case the parameter is $\mu$ _D) in order to select the correct test statistic.
