Question: Re do Exercise 6 above as a Chi square test Did you

Re-do Exercise 6 above as a Chi-square test. Did you get the same answer? Did you expect to?
In exercise
A random sample of new members of a large downtown fitness club was selected, and tracked over six months. Of the 60 members who joined the club to participate in fitness classes, 38 were still working out regularly six months after joining. Of the 80 members who joined to work out with a personal trainer, 60 were still working out regularly six months after joining. At the 2.5% level of significance, is there evidence of a difference in the proportion of new members still working out regularly six months after joining the club when comparing those who attend fitness classes and those who work out with a personal trainer?
