You are using quota sampling to enroll 100 swimmers in a study on lung capacity. You want 25% of your sample to be those who compete at 100m or less distances and 50% to be swimmers who compete at 100m-500m distances and 25% to be swimmers who compete at 500m distances. You begin enrolling for your study at 5am at the pool. By 9 AM you have all of your 100-500m swimmers enrolled, and all of your 500m swimmers enrolled. You still need four more swimmers who compete at 100m or less. You should:
A) keep enrolling all swimmers who are interested
B) only enroll swimmers who compete at 100m or less
C) adjust your sample size and calculate your estimates with n=96
D) enroll the next four swimmers to arrive and complete your sample
