A researcher wishes to estimate the mean resting heart rate for long-distance runners. A random sample of 12 long-distance runners yields the following heart rates in beats per minute:
61 71 62 64 60 69 78 81 65 60 63 71
a. Use this data to obtain a point estimate of the mean resting heart rate for all long-distance runners. Interpret this value.
b. Find a 93% confidence interval of the mean resting heart rate for all long-distance runner with the TI-calculator. Include the commands.
c. Interpret the interval found in part b.
d. Find and explain the margin of error.

The mean resting pulse rate for men is 72 beats per minute. A
simple random sample of men who regularly work out at Mitch's Gym
is obtained and their resting pulse rates (in beats per minute) are
listed below. Use a 0.05 significance level to test the claim that
these sample pulse rates come from a population with a mean less
than 72 beats per minute. Assume that the standard deviation of the
resting pulse rates of all men who...

The resting heart rate for an adult horse should average about
μ = 42 beats per minute with a (95% of data) range from 18
to 66 beats per minute. 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) The empirical rule indicates that for a symmetrical and
bell-shaped distribution, approximately 95% of the data lies within
two standard deviations of the...

A researcher at UniSA’s School of Health Sciences believes that
energy drink consumption may increase heart rate. She believes that
heart rate in beats per minute (bpm) is normally distributed with
an average of 70 bpm for adults. To test her belief, she takes a
random sample of 25 adults who regularly consume energy drink.
Their heart rates are 65, 64, 75, 79, 60, 84, 63, 91, 81, 98, 92,
69, 78, 85, 88, 87, 70, 80, 73, 74, 83,...
