Question

If we are interested in testing whether the mean of items in population 1 is larger than the mean of items in population 2, the A)null hypothesis should state $\mu$₁ - $\mu$₂ < 0 B)null hypothesis should state $\mu$₁ - $\mu$₂ > 0 C)alternative hypothesis should state $\mu$₁ - $\mu$₂ > 0 D)alternative hypothesis should state $\mu$₁ - $\mu$₂ < 0

The null hypothesis should state that there is no significant difference between the mean of items in population 1 and population 2. Therefore, the alternative hypothesis should state that the mean of items in population 1 is larger than the mean of items in population 2, which is represented by option C.
