Question

1. What is the mean BMI of this population? 2. How do these adults’ BMI value stack up against the rest of the country? 3. Nationally, 47% of adults in the US have hypertension (see the CDC article for more details). Does this population have a significantly lower percentage of adults with hypertension? Use 0.01. Use your sample to create a 95% confidence interval for the mean BMI value of this population. Based on your confidence interval, compare the BIM of these adults with the national mean of 26.55 mean. Include a brief written report that includes complete demonstrations of the statistical procedures you used and your conclusions for questions 1-2 Determine whether your sample provides statistical evidence that this company’s population of adults have a lower rate of Hypertension than the national average. Set alpha at 0.01.

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 + ...
