- In a previous example results were given for a survey of students in a statistics class who measured the lengths of their right and left feet to the nearest millimeter. Suppose the right and left foot measurements were equal for 118 of the 223 students. Assuming that this class is representative of all college students, is there convincing statistical evidence that the proportion of college students whose feet are the same length differs from one-half? Go through the five steps of hypothesis testing for this situation. Use the p-value to make a reasonable conclusion. A USE SALT Determine the null and alternative hypotheses. (Enter = for as needed.) Ho H Verify that necessary data conditions are met. We are told that we can 8v assume the sample is representative of all college students. In addition we find np.
