We model the difference in means in the simple way of using a standard normal curve.03/30/20
The sampling distribution of differences between means approximates a normal curve distribution whose mean is zero

standard normal distribution, mean is zero, and standard deviation is one
however, you test the sample for differences of two means... if zero, then the means are equal
Null Hypothesis: mean1 - mean2 = 0
Alternate Hypothesis: the means are different
