In a study comparing population 1 and population 2, the sample mean difference was
s_d=$830, and the sample standard deviation was
s_d=$1,124.
What are the appropriate null and alternative hypotheses to test for no difference between the populations?
A) Null Hypothesis (H ₀): There is a difference between the means of population 1 and population 2. Alternative Hypothesis H ₁): There is no difference between the means of population 1 and population 2.
B) Null Hypothesis (H ₀): There is no difference between the means of population 1 and population 2. Alternative (H ₁): There is a difference between the means of population 1 and population 2.
C) Null Hypothesis (H ₀ ): The mean difference between population 1 and population 2 is $830. Alternative Hypothesis (H ₁): The mean difference between population 1 and population 2 is not $830.
D) Null Hypothesis (H ₀ ): The mean difference between population 1 and population 2 is zero. Alternative Hypothesis (H ₁): The mean difference between population 1 and population 2 is not zero.
