A student has taken 4 area exams designed to measure particular intellectual abilities. The following table identifies each test, summarizes its characteristics, and provides the student’s score on it. Assume that the possible scores on each test are normally distributed. Area Test ? ? Student’s Score Verbal Ability 58.50 6.50 63.00 Visualization 110.00 15.00 102.50 Memory 85.00 11.50 98.00 Spatial Relations 320.00 33.50 343.00 a. Change each student’s score to its z-score equivalent b. On which test did the student score in the highest position? c. On which test did the student score in the lowest position? d. What is the percentile rank of the student’s Verbal Ability? e. What percentage of the students who took the Spatial Relations test scored higher than the student? f. Between what two scores on Memory did the middle 95% of students lie? g. What percent of students had scores between X = 95 and X = 110 on Visualization?

Seating at GC Thinking back again to the m111survey data frame, recall that the variable seat records where each subject prefers to sit in a classroom: Front, Middle, or Back. Here is a table of the results: gcSeat <- xtabs(~seat,data=m111survey)gcSeat ## seat## 1_front 2_middle 3_back## 27 32 12 Now at Georgetown most classrooms are fairly small, with at about four rows actually in use: the first row is obviously the Front; most people would think of the second and third rows as the Middle; the fourth row would count as the Back. If preferences for the four rows are exactly the same out there in the GC population, then one would expect that: 25% of the population prefers the Front; 50% prefer the middle (twice as many rows in the Middle, after all); 25% prefer the back. We wonder if the available data provide strong evidence against the idea of equal preference among all four rows. The results of the chi-sqaure test are as follows: ## Chi-squared test for…
Laboratory Exercise on One Way ANOVA for Correlated Means Problem: Do colors affect mood? You are particularly interested to know which color gives people a sense of serenity and peacefulness. You conduct an experiment by making participants stay for 20 minutes inside a room painted with a particular color (e.g., Red, Orange, Yellow, Green, Blue). With the use of temperature-sensitive cameras, you record the average body temperature of each individual during their stay inside each room (i.e., lower body temperatures are associated with feelings of calmness and relaxation; higher body temperatures - stimulation, excitement). Results are presented on the table. Red 43 39 41 42 45 41 Orange Yellow Green 39 38 33 43 39 42 44 35 40 39 39 39 38 35 34 37 36 33 Blue 31 34 32 32 35 34 A.
