... E.g.: if of 15 people, 9 owned their homes, 3 were renting and 3 paying a mortgage, the there would be (9x3) + (9x3) + (3x3) = 63 ways in which pairs of cases could be made with each having voted for a different party. This is the number of observed differences: the numerator of the formula. Howeve ...

In this case we are defining a one-tailed hypothesis since we will only be concerned with the lower half of the distribution where the sample means are less than the population mean. Therefore, H0: μ = 175 and Ha: μ < 175. The area of ...
