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 At CSULB, do male and female students show different levels of school spirit?
