Question

We can be 99% confident that the true population mean MHI score for Democrats is between (lower limit) to (upper limit).

Imagine that a public health organization would like to deploy a support program to populations where at least 50% of the population experiences life conditions that are at least moderately stressful (defined as a mean MHI score of 7 or higher). Should this program be deployed to Democrats?

The following table shows summary data for the Mental Health Index (MHI) scores for respondents, organized by political party identification. A higher score indicates that a respondent
experienced more mental health issues in the past 7 days, including anxiety, hopelessness, and trouble sleeping.

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 + ...
