1. Consider the folllowing data: Description Population 1 Population 2 Sample Mean 31.6 26.8 Population Variance 91.9 90.0 Sample Size 20 26 Construct a 99% confidence interval for the difference between population means. (FORMATTING: Negative values should be indicated by a minus sign, no spaces! Round intermediate calculations to 6 decimal places and final answer to 2 decimal places). a. Indicate the margin of error (6 decimal places): b. Indicate the lower limit of the confidence interval (2 decimal places):...

Define what is meant by rationing of health care. In what age-based population is health care rationing most likely to occur? How might this be done? (Give two examples, and provide references as appropriate.) (200 words only)
##### Given a population with a mean of µ = 100 and a variance σ2 = 13,...
Given a population with a mean of µ = 100 and a variance σ2 = 13, assume the central limit theorem applies when the sample size is n ≥ 25. A random sample of size n = 28 is obtained. What is the probability that 98.02 < x⎯⎯ < 99.08?

Suppose you are tasked with explaining health care and the health care system in the united states to either: a) a five year old or b) an anthropologist from another planet (who has access to a basic translator) In either case, assume the individual knows that people get sick and that resources are scarce. Everything else you must explain simply. (3pts) Your answer should include: Demand uncertainty, medical effectiveness uncertainty, Medicare, Medicaid, health insurance, hospital, doctor/provider.

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....
