In testing for differences between the means of two independent populations, the null hypothesis is: A)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 2$ B)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 0 .$ C)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } 0$ D)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 }

Question

In testing for differences between the means of two independent populations, the null hypothesis is:

A)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 2$ 
B)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 0 .$ 
C)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } > 0$ 
D)$H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } < 2$

The Answer is B

In Testing for Differences Between the Means of Two Independent H0:μ1−μ2=2H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 2H0​:μ1​−μ2​=2

In Testing for Differences Between the Means of Two Independent $H _ { 0 } : \mu _ { 1 } - \mu _ { 2 } = 2$
