In a study of 235 adults, the average heart rate was 82 beats per minute. Assume the population of heart rates is known to be approximately normal, with a standard deviation of 5 beats per minute. What does a margin of error of 0.8 for the 98% confidence interval of the average beats per minute mean?
There is a 2% chance that the population mean is less than 82 beats per minute.
There is a 2% chance that the population mean is more than 82 beats per minute.
There is a 98% chance that the population mean is between between 77 and 87 beats per minute.
There is a 98% chance that the population mean is between 81.2 and 82.8 beats per minute.
