... The t Statistic for an Independent-Measures Research Design • As with all hypothesis tests, the general purpose of the independent-measures t test is to determine whether the sample mean difference obtained in a research study indicates a real mean difference between the two populations (or treatme ...

... with any measured quantity. There is then the question of how the quantity and its uncertainty are best represented. We will see that even the most straightforward observations have an uncertainty, and two people observing the same quantity may report different values. The simplest case to be consid ...

... a. Test the hypothesis that the mean body fat for males in this category is 12 at α = 0.05 level. Solution: From this sample of size 36, the mean and standard deviation are 14.4 and 6.95 respectively. The sequence of steps in a classical test of hypotheses is as follows: 1) H0: = 12 and HA: ¹ 12 ...
