The resting heart rate for an adult horse should average about = 46 beats per minute

Question:

The resting heart rate for an adult horse should average about μ = 46 beats per minute with a (95% of data) range from 22 to 70 beats per minute, based on information from the Merck Veterinary Manual (a classic reference used in most veterinary colleges). Let x be a random variable that represents the resting heart rate for an adult horse. Assume that x has a distribution that is approximately normal.
(a) Estimate the standard deviation of the x distribution. Hint: See Problem 31.
(b) What is the probability that the heart rate is fewer than 25 beats per minute?
(c) What is the probability that the heart rate is greater than 60 beats per minute?
(d) What is the probability that the heart rate is between 25 and 60 beats per minute?
(e) A horse whose resting heart rate is in the upper 10% of the probability distribution of heart rates may have a secondary infection or illness that needs to be treated. What is the heart rate corresponding to the upper 10% cutoff point of the probability distribution?
Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
