23. In a survey done by the family-friendly group Ferguson Privacy Infiltration Bureau, they found

that the average height of Math 136 students is 62.4 inches. Some people felt this average was

too high, and so the Ferguson Observation Agency conducted a survey and found that of the 46

Math 136 students randomly surveyed, the average height was 58.1 inches with a standard

deviation of 5.3. Use the a = .05 level of significance. You can assume the height of one student

doesn;t affect the height of another student.
