Question: In 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. The right and left foot measurements were equal for 103 of the 215 students. Assuming that this class is representative of all college students, is there 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 a = .05.
Example: A Two-Sided Test: If Your Feet Don't Match, Is the Right One More Likely to Be Longer or Shorter? Students in a statistics class measured the lengths of their right and left feet to the nearest millimeter. The right and left foot measurements were equal for 103 of the 215 students, but the two foot lengths were different for 112 students.
