Question

Question 6 (2 points) In testing for differences between the means of two paired populations, an appropriate null hypothesis would be: Ho: Ud= 2 Ho: Md = 0 HO: Hd > 0 Ho: Md < 0

Answer 1

Question-6

To test the difference between the means of two paired populations.

The two paired populations difference is denoted by,

$\therefore \mu_{d}=\mu_{1}-\mu_{2}$

The appropriate null hypothesis would be,

$\therefore H_{0}:\mu_{d}=0$

The appropriate alternative hypothesis would be

$\therefore H_{1}:\mu_{d}\neq 0$

Or, $\therefore H_{1}:\mu_{d}< 0$

Or, $\therefore H_{1}:\mu_{d}>0$
