Here is the question:

Question 1 2 pls The owner of a chain of six local gyms, Ms. Crane, would like to know the average amount of time spent at her gyms on a particular Sunday' Her gyms are very busy and so at each gym, she has a sign in sheet where visitors sign in when they enter and record the time, and sign out when they are leaving, also indicating the time She decides she'd like a simple random sample of 20 gym-goers on the particular Sunday and so she randomly selects one of her local gyms, and at closing, from her sign-in sheet, randomly selects 20 names and calculates the time spent at the gym. From there she can estimate the average amount of time spent Assuming each gym gets at least 20 visitors on that Sunday, is her sample of 20 names a simple random sample? If not, why not? 0 No since she did not ensure she got names from each gym. 0 No, since not all possible selections of 20 names from the sheets are possible. 0 No since some visitors on that Sunday had no chance of being part of her sample. 0 Yes it is. O No since not every gym-guer went to the gym that Sunday
