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.

Student	Pulse
Perpectual Bempah	68
Megan Brooks	68
Jeff Honeycutt	83
Clarice Jefferson	70
Crystal Kurtenbach	90
Janette Lantka	69
Kevin McCarthy	77
Tammy Ohm	79
Kathy Wojdya	83

The population mean pulse is approximately

76.376.3

beats per minute.

(Type an integer or decimal rounded to the nearest tenth as needed.)

Part 2

(b) Determine the sample mean pulse of the following two simple random samples of size 3.

Sample 1: {Kevin, Megan, Clarice}

Sample 2: {Tammy, Kathy, Jeff}

The mean pulse of sample 1 is approximately

beats per minute.

(Round to the nearest tenth as needed.)

Definition Definition Number of subjects or observations included in a study. A large sample size typically provides more reliable results and better representation of the population. As sample size and width of confidence interval are inversely related, if the sample size is increased, the width of the confidence interval decreases.
