At CSULB, do male and female students show different levels of school spirit? I've often wondered about this when I walk across campus. On one of my walks I noticed that 7 out of 100 randomly- sampled students were male and were wearing CSULB attire. On another one of my walks I noticed that 1 in 10 female students were wearing CSULB attire. It is also known that the student body is 57% female. Based on these data, answer questions 27-30. Hint: it will help to draw this as a probability tree. 23) What is the probability that a randomly selected student is male and not wearing any CSULB attire? e) 0.07 f) 0.16 g) 0.36 h) 0.93 24) What is the probability that a randomly selected student is female and not wearing any CSULB attire? a) 0.10 b) 0.51 c) 0.57 d) 0.90 26) In testing whether wearing CSULB attire is independent of sex, which is the appropriate (in)equality? a) 0.074 +0.057, therefore not independent b) 0.070 +0.074, therefore not independent c) 0.070 +0.10, therefore not independent d) 0.070 = 0.070, therefore independent
