It is known that 10% of students in Statistics are absent from the class. Suppose 100 students are randomly called to check their class attendance. Let X be the number of absentees. (a) Find the exact P (X = 8). (b) Conduct a normal approximation to P (X

Factorial ANOVA

Treating Test Anxiety. Relaxation Training (RT) and Physical Fitness Training (PFT) were compared as methods for treating test anxiety among male and female junior pilots employed for a major airplane carrier. Two random samples of male and female pilots were used as participants. After two weeks of their assigned training, the pilots were measured for anxiety during a regular flying test. The data are presented below (1 = low anxiety, 10 = high anxiety). 

	Relaxation	Physical
	5	6
	6	5
Male	6	3
	9	7
	7	7
	6	2
	5	3
Female	5	1
	8	1
	5	2

 

(a) Perform a complete analysis and interpretation of the results.

(b) What would you suggest to airline about training junior pilots regarding the appropriate

therapy for those with test anxiety problems?
