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 (a) Determine the population mean pulse. parts (a) to (c). The population mean pulse is approximately beats per minute. (Type an integer or decimal rounded to the nearest tenth as needed.) Student Pulse Perpectual Bempah 81 (b) Determine the sample mean pulse of the following two simple random samples of size 3. Megan Brooks 76 Jeff Honeycutt 74 Sample 1: {Jeff, Kathy, Perpectual} Sample 2: {Crystal, Jeff, Tammy} Clarice Jefferson 70 Crystal Kurtenbach 77 The mean pulse of sample 1 is approximately beats per minute. Janette Lantka 74 (Round to the nearest tenth as needed.) Kevin Mccarthy 88 Tammy Ohm 63 The mean pulse of sample 2, is approximately beats per minute. (Round to the nearest tenth as needed.) Kathy Wojdya 66 (c) Determine if the means of samples 1 and 2 overestimate, underestimate, or are equal to the population mean. The mean pulse rate of sample 1 the population mean. The mean pulse rate of sample 2 the population mean
