Question: A statistics student heard that an individuals arm span is equal to the individuals height. To test this hypothesis, the student used a random sample

A statistics student heard that an individual€™s arm span is equal to the individual€™s height. To test this hypothesis, the student used a random sample of 10 students and obtained the following data.

(a) Is the sampling method dependent or independent? Why?
(b) Does the sample evidence contradict the belief that an individual€™s height and arm span are the same at the a = 0.05 level of signiï¬cance?

Student: Height (inches) 59.5 69 77 59.5 74.5 Arm span (inches) 6 65.5 76 63 74 Student: Height (inches)63 15 67.5 73 69 Arm span (inches) 66 61 69 70 71 4 6 10
