Suppose data made available through a health system tracker showed health expenditures were $10,348 per person in the United States. Use $10,348 as the population mean and suppose a survey research firm will take a sample of 100 people to investigate the nature of their health expenditures. Assume the population standard deviation is $2,500.
What is the probability the sample mean will be within ±$150 of the population mean? (Round your answer to four decimal places.)

2. The latest available data showed health expenditures were
$8086 per person in the United States or 17.6% of gross domestic
product (Centers for Medicare & Medicaid Services website,
April 1, 2012). Use $8086 as the population mean and suppose a
survey research firm will take a sample of 100 people to
investigate the nature of their health expenditures. Assume the
population standard deviation is $2500. a) Identify the sampling
distribution of the mean amount of health care expenditures for...

Suppose overall health care spending rose from $7000 per person
in 2006 to $7700 per person in 2007. [1] Calculate both the
absolute change and percentage change in health care spending per
person from 2006 to 2007. [2] Using 2006 as your starting year
(2006 = year 0), determine an exponential equation that calculates
the amount of health care spending over time assuming the annual
percentage change stays the same. Clearly identify the variable
names and symbols in your equation....

Annual expenditures for prescription drugs was $838 per
person in the Northeast of the country. A sample of 60 individuals
in the Midwest showed a per person annual expenditure for
prescription drugs of $745. Suppose the population standard
deviation is $300. Follow the steps below to develop a hypothesis
test to determine whether the sample data support the conclusion
that the population annual expenditure for prescription drugs per
person is lower in the Midwest than in the Northeast.
