Question

The following data represent the pulse rates (beats per minute) of nine students enrolled in a statistics course. Treat the nine students as a population. Complete parts (a) to (c). (a) Determine the population mean pulse The population mean pulse is approximately 80.8 beats per minute (Type an integer or decimal rounded to the nearest tenth as needed) (b) Determine the sample mean pulse of the following two simple random samples Sample 1 (Jeff, Clarice, Crystal) Sample 2: (Perpetual, Kathy, Clarice) The mean pulse of sample 1 is approximately beats per minute. (Round to the nearest tenth as needed)

Explanation / Answer

The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.

Mean pulse for sample 1 = (89+73+82)/3 = 81.7

Mean pulse for sample 2 = (70+73+88)/3 = 77
