What parameter needs to be estimated? the resting pulse rates of 92 male students the mean resting pulse rate for all male students the mean resting pulse rate for a sample of 92 male students the resting pulse rates for all male students

To estimate the parameter of interest, you're looking at the mean resting pulse rate for all male students. This population parameter provides valuable information, as it reflects the average pulse rate across the broader group, going beyond just your sample of 92 students. However, when you only have those 92 male students, it's not feasible to know the exact mean pulse rate for the entire population. Instead, you can calculate the sample mean as an estimate, which provides insight but comes with some uncertainty. This is where statistical methods, such as confidence intervals, shine!
