Refer to the data set in the accompanying table. Assume that the paired sample data is a simple random sample and the differences have a distribution that is approximately normal. Use a significance level of 0.10 to test for a difference between the number of words spoken in a day by each member of 30 different couples. Click the icon to view the data. In this example d is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the number of words spoken by a male minus the number of words spoken by a female in a couple.
