Suppose that you take a random sample of 30 healthy American men...What is the z-score corresponding to a mean blood pressure of 79 mmHg for this sample?What is the likelihood that in this sample, the mean diastolic blood pressure is above 79 mmHg? The diastolic blood pressure for a population of healthyAmerican men is normally distributed, with mean 82mmHg and standard deviation 10 mmHg. Treat thesenumbers as the parameter values for healthy Americanmales, and use this scenario throughout the activity.

The mean is 82 and the standard deviation is 10.

Question

Suppose that you take a random sample of 30 healthy American men...

What is the z-score corresponding to a mean blood pressure of 79 mmHg for this sample?

What is the likelihood that in this sample, the mean diastolic blood pressure is above 79 mmHg?

The diastolic blood pressure for a population of healthy
American men is normally distributed, with mean 82
mmHg and standard deviation 10 mmHg. Treat these
numbers as the parameter values for healthy American
males, and use this scenario throughout the activity.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
