3.2 x 10^7 = 32,000,000
4.5 x 10^9 = 4,500,000,000
32,000,000 x 4,500,000,000 = 1.44e17
9 divided by 7.5 equals 1.2
As with comparing two population proportions, when we compare two population means from independent populations, the interest is in the difference of the two means. In other words, if is the population mean from population 1 and is the population mean from population 2, then the difference is μ 1 − μ 2 .
