Given a pulse rate 100 beats per minute. Does this value appear to be unusual If we are given a mean pulse rate of 70 and standard deviation of 12? Explain.
as we know that 2 std deviation away values from mean are considered to be unusual
distance of 100 beats per minute from mean in terms of standard deviation =(100-70)/12=2.5
as it is higher then absolute value of 2 ; therefore 100 beats per minute appear to be unusual

Assume that an adult female is randomly selected. Suppose females have pulse rates that are normally distributed with a mean of 79.0 beats per minute and a standard deviation of 12.5 beats per minute. Find the probability of a pulse rate between 62 beats per minute and 73 beats per minute. (Hint: Draw a graph.) The probability is _______ .
A certain group of test subjects had pulse rates with a mean of 81.9 beats per minute and a standard deviation of 11.8 beats per minute. Would it be unusual for one of the test subjects to have a pulse rate of 125.5 beats per minute? Minimum "usual" value? Maximum "usual" value? Is 125.5 beats per minute an unusual pulse rate?
A certain group of test subjects had pulse rates with a mean of 82.6 beats per minute and a standard deviation of 10.2 beats per minute. Would it be unusual for one of the test subjects to have a pulse rate of 73.0 beats per minute. Minimum "usual" value =___ beats per minute Maximum "usual" value =____ beats per minute Would it be unusual for one of the test subjects to have a pulse rate of 73.0 beats per minute?
A certain group of test subjects has pulse rates with a mean
of 84.2 beats per minutes and a standard deviation of 10.8 beats
per minutes. Would it be unusual for one of the test subjects to
have a pulse rate of 95.8 beats per minute?

Assume that females have pulse rates that are normally distributed with a mean of μ=76.0 beats per minute and a standard deviation of σ=12.5 beats per minute. Complete parts (a) through (c) below.a. If 1 adult female is randomly selected, find the probability that her pulse rate is between 72 beats per minute and 80 beats per minute.The probability is nothing.
