average adult heart rate?
Homework Answers
Heart rate can be defined as the number of times heart beats or contracts in a minute. Heart rate is the beats per minute.
When the blood is pumped out of the heart it contracts. These contractions in a minute are known as heart rate.
Heart beat is controlled through sympathetic and parasympathetic stimulation of the heart.
Factors affecting heart beat include exercise, stress, fever, pregnancy, anxiety, depression, temperature, altitude.
Normal adult heart rate is 60-100bpm. When the heart rate is more than 100 bpm it is known as tachycardia. When heart beat is less than 60 bpm it is known as bradycardia.
When the heart rate becomes irregular or abnormal the condition is termed as arrhythmia.
Heart rate is almost equal to the pulse rate and can be measured by counting radial pulse. It can also be monitored through ECG.

The resting heart rate for healthy adult horses are normally distributed with an average of 46 beats per minute with a standard deviation of 8 beats per minute. A horse whose resting heart rate is in the upper 10% of the distribution of heart rates may have a secondary infection or illness that needs to be treated. How fast must a healthy horse’sheart be beating to fall into this at-risk group?

Let x be a random variable that represents the resting heart rate for an adult horse. Assume that x has a distribution that normal. The middle 95% of the distribution has a range of heart rates between 25 to 71 beats per minute. Find the mean and standard deviation of this distribution.

In an adult, a heart rate of 60-100 beats/min is a normal sinus rhythm (NSR). A heart rate at or above 101 beats/min is called tachycardia, but in young children, this rate would be considered normal. Heart rates belovw 60 beats/min are normal for highly conditioned individuals, but in most adults this is bradycardia I. Calculate the heart rate for the ECGx.0 Diagnosis P-R intervals: Normal P-R intervals are between 0.12 and 0.2 seconds, averaging about 0.16 seconds. P-F intervals...

In a random sample of 40 cross-fit participants, the average resting heart rate for the sample was 76.3 Beats per Minute. Assume the population standard deviation is 12.5 Beats per Minute. Construct a 99% confidence Interval for the average resting heart rate for the population [71.2, 81.4] [73.3, 79.3] [75.2, 83.4] [78.3, 86.9]

Suppose that the average resting heart rate for men over 19 years old is 70 beats per minute (bpm) with a standard deviation of 8 bpm. 1. What is the probability that a randomly selected male 19 years old or older will have a resting heart rate of more than 83?

In this assignment, you will test for a significant difference between the average resting heart rate of males and the average resting heart rate of females in your heart rate data. You have observed that the mean rates are not exactly the same but are they significantly different? You may use either of the two methods for testing a hypothesis illustrated in Realizeit: compare the two confidence intervals or use the data analysis tool to run a two-sample test with...
