Question

1. while standing, find your pulse and time it for 30 seconds. to find the number of beats per minute, multiply that number by 2. record your data in table 2. 4. repeat step 3 two more times. calculate the average beats per minute. table 2: standing pulse (2 pts)

trial 1 (bpm)	trial 2 (bpm)	trial 3 (bpm)	average (bpm)

Explanation:

This is an experimental procedure rather than a problem with a specific answer to calculate directly. However, if we assume some sample data (for example, let's say Trial 1 = 70 bpm, Trial 2 = 72 bpm, Trial 3 = 68 bpm) to show how to calculate the average:

Step 1: Sum the three trials

To find the sum of the three trial values, we add them together. The formula for the sum \( S \) of three numbers \( x_1 \), \( x_2 \), \( x_3 \) is \( S=x_1 + x_2+x_3 \).
Given \( x_1 = 70 \), \( x_2=72 \), \( x_3 = 68 \), then \( S=70 + 72+68=210 \).

Step 2: Calculate the average

The formula for the average \( A \) of \( n \) numbers is \( A=\frac{\text{Sum of numbers}}{n} \). Here \( n = 3 \) (since there are 3 trials) and the sum \( S = 210 \). So \( A=\frac{210}{3}=70 \).

Answer:

If we use the sample data (Trial 1 = 70, Trial 2 = 72, Trial 3 = 68), the average is 70 bpm. (Note: You need to use your actual measured data from the experiment to fill in the table and calculate the average following the same steps.)
