Question

A physician wants to develop criteria for determining whether a patient’s
pulse rate is atypical, and she wants to determine whether there are significant differences between
males and females. Use the data contained in the sheet corresponding to pulse rates in the attached Excel file and
- Construct a 95% confidence interval estimate of the mean pulse rate for males.

- Construct a 95% confidence interval estimate of the mean pulse rate for females.
- Compare the preceding results. Can we conclude that the population means for males and
females are different? Why or why not?

Can we conclude that the population means for males and

females are different? Why or why not?

Answer:

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 + ...
