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.

QUESTION 2 An environmentalist wanted to determine if the mean acidity of rain differed among Ipoh, Johor Bahru and Kuantan. He randomly selected six rain dates at each city and obtained the following data: Table 2 Ipoh 5.10 5.00 4.91 5.12 4.78 5.20 Johor Bahru 4.80 4.15 4.42 4.65 4.87 4.10 Kuantan 5.45 6.23 5.55 5.10 5.42 5.25 Answer the following questions without using any output from any software. a) Construct a complete Analysis of Variance table. b) At <= 0.05, test whether the mean acidity of rain is different among the three cities. c) Based on the answer in (a) and (b), write a brief conclusion on the mean acidity of rain among Ipoh, Johor Bahru and Kuantan.
Lecture(8.4): Researchers were interested in whether the number of books children carried differed between gender. It was hypothesized that girls would carry more books than boys.Twenty children were recruited and matched based on age and SES..Researchers then collected the number of the age of the appropiate books the children carried. A Summary of the result is given below: Girls 15 7 22 13 26 14 12 11 18 30 Boys 12 10 16 8 17 9 15 10 20 15 Test the hypotheses at (alpha=0.05) level of signifance
5. A recent study indicates that simply giving college students (n-30) a pedometer can result in increased walking (Jackson & Howton, 2008). Students were given pedometers for a 12-week period, and asked to record the average number of steps per day during weeks 1, 6, and 12. a. Which variables are described in this scenario and what are their scales of measurement? b. Which test should you use?
An investigator predicts that students taking an achievement test in the morning will perform differently than students taking the same test in the afternoon. Eight students are assigned to take the test in the morning and 8 students are assigned to take the test in the afternoon. Run an independent samples t-test and summarize findings using an alpha level of .05, two-tailed. Also construct a bar graph to graphically represent your results. Morning Group: 25, 31, 44, 36, 29, 42, 39, 41 Afternoon Group: 22, 25, 24, 27, 33, 28, 31, 34
The estimated labor cost associated with a particular proposal is based on the number of plantings of trees, shrubs, and so on to be used for the project. For cost-estimating purposes, managers use two hours of labor time for the planting of a medium-sized tree. Actual times from a sample of 10 plantings during the past month follow (times in hours). 1.6 1.5 2.6 2.3 2.5 2.3 2.6 3.0 1.3 2.3 What is the test statistic?
