In the US, the systolic blood pressure of a randomly selected patient has an unknown distribution with a
mean of 123 mmHg and a standard deviation of 16.4 mmHg. Let X be the systolic blood pressure of a
randomly selected patient and let X be the average systolic blood pressure of a random sample of size 41.
