TABLE 2.5 Student teachers are trained to develop lesson plans, on the assumption that the writ- ten plan will help them to perform successfully in the classroom. In a study to assess the relationship between written lesson plans and their implementation in the class- room, 25 lesson plans were scored on a scale of 0 to 34 according to a Lesson Plan Assessment Checklist. The 25 scores are shown in Table 2.5. Use Tchebysheff's The- orem and the Empirical Rule (if applicable) to describe the distribution of these assessment scores.

Students were told to suppose that they were planning to have a large two-topping pizza delivered to their residence that evening. The students had to decide between ordering from Pizza Hut at a reduced price of $8.49 (the regular price for a large two-topping pizza from Oxford Pizza Hut at the time was $11.49) and ordering a pizza from a different pizzeria. The results from this question are summarized in the accompanying contingency table. Complete parts (a) through (d). GENDER Pizza Hut OtherFemale 4 12Male 8 16 a.
