Dr. Cyril conducts a simple random sample of 500 men who became fathers for the first time in the last year. He finds that 23% of them report being unsure of their ability to be good fathers, plus or minus 4%. What does this mean?

A) The true percentage of fathers who feel this way is 23%.

B) If this study was done many times, the estimate of father uncertainty would be 23% about 4% of the time.

C) We can be 4% sure that the estimate of father uncertainty would be 23% of fathers.

D) If the study was done many times, the estimate of father uncertainty would be between 19% and 27%.
