claim: the mean pulse rate (in beats per minute) of adult males is equal to 69 bpm. for a random sample of 147 adult males, the mean pulse rate is 69.2 bpm and the standard deviation is 10.6 bpm. find the value of the test statistic.

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
