Question
The accompanying 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) through (c). : Click the icon to view the data on the students' pulse rates. (a) Compute the population standard deviation. beats per minute (Round to one decimal place as needed.) (b) Determine the sample standard deviation of the following three simple random samples of size 3. Sample 1: {Janette, Kevin, Tammy} Sample 2: {Megan, Kevin, Tammy} Sample 3: {Crystal, Jeff, Kevin} The sample standard deviation, s, of sample 1, {Janette, Kevin, Tammy}, is (Round to one decimal place as needed.) beats per minute. The sample standard deviation, s, of sample 2, {Megan, Kevin, Tammy}, is beats per minute. (Round to one decimal place as needed.) The sample standard deviation, s, of sample 3, {Crystal, Jeff, Kevin}, is beats per minute (Round to one decimal place as needed.) (c) Which samples underestimate the population standard deviation? Which overestimate the population standard deviation? Sample 1 V the population standard deviation. Sample 2 V the population standard deviation. Sample 3 V the population standard deviation.

Expert Solution
Step 1

(a)

Step1: Enter the data in the worksheet. The screenshot will be:

Pulse 71 72 Student Perpectual Bempah Megan books Jeff Honeycutt Clarice jefferson Crystal Kurtenbach Janette lantka Kevin Mc

Step 2: Use formula = {\rm{stdev}}{\rm{.p}}\left( {} \right) to calculate population standard deviation as:

E3 x fc =STDEV.P(B2:B10) ДА BC 1 Student Pulse 2 Perpectual Bempah 71 3 Megan books 72 Population standard deviation 5.6328|

Part a

The population standard deviation is computed as 5.6328.
