An aging sheep cat, Mimi, gets regular checkups. Let X be a
random variable that represents the cat's resting heart rate. From
past experience, the vet knows x has a normal distribution with
= 12. This particular cat breed is known to have an average heart
rate of 115 beats per minute. From Mimi's last six checkups, her
heart rate measured: 93, 109, 110, 89, 117. At
= 0.05, is Mimi's heart rate slowing?
Below are the null and alternative Hypothesis,
Null Hypothesis: μ = 115
Alternative Hypothesis: μ < 115
Test statistic,
z = (xbar - mu)/(sigma/sqrt(n))
z = (103.6 - 115)/(12/sqrt(5))
z = -2.12
P-value Approach
P-value = 0.0170
As P-value < 0.05, reject the null hypothesis.
