(08.05 lc) in a study of 205 adults, the average heart rate was 75 beats per minute. assume the population of heart rates is known to be approximately normal, with a standard deviation of 8 beats per minute. what does a margin of error of 1.1 for the 95% confidence interval of the average beats per minute mean? a) there is a 95% chance that the population mean is between 67 and 83 beats per minute. b) there is a 95% chance that the population mean is between 73.9 and 76.1 beats per minute. c) there is a 5% chance that the population mean is less than 75 beats per minute. d) there is a 5% chance that the population mean is more than 75 beats per minute.
