Case Analysis - Wentworth Medical Center
As part of a long-term study of individuals 65 years of age or
older, sociologists and physicians at the Wentworth Medical Center
in upstate New York investigated the relationship between
geographic location and depression. A sample of 60 individuals, all
in reasonably good health, was selected; 20 individuals were
residents of Florida, 20 were residents of New York, and 20 were
residents of North Carolina. Each of the individuals sampled was
given a standardized...

The General Social
Survey collects data on demographics, education, and work, among
many other characteristics of US residents. The histograms below
display the distributions of hours worked per week for two
education groups: those with and without a college degree.
Suppose we want to estimate the difference between the average
number of hours worked per week by all Americans with a college
degree and those without a college degree. Summary information for
each group is shown in the tables.

Part A. In the past it has been found that the arrival time have
a population mean value of μ = 13 and a population standard
deviation of σ = 6.26. Using the given data, test whether this mean
has changed. Use the critical value approach to test the
hypothesis. The significance level alpha is set at 0.05 . The
original data of time taken is given below. Show the process by
using excel (Formulas).

A study was conducted to investigate the effectiveness of three
different methods to lower the blood pressure of individuals
diagnosed with high blood pressure. The researcher was interested
in the reduction of diastolic blood pressure in the subjects that
were assigned to three groups. The first group took medication, the
second group engaged in daily aerobic exercises, and the third
group was prescribed a plant-based diet. The subjects were placed
in their regiments for four weeks. Diastolic blood pressure was...
