You are asked to illustrate the ideas in the paper using the NHANES data set posted with

the term project. You are asked to analyze this data set using traditional methods of analysis and

using sample survey methods. The following variables are to be used:

In this data analysis, proceed as follows:

1. Analyze the whole data set treating it as the population.

2.Take a 10% stratified sample, stratifying on age and repeat the analysis, using both the

traditional survey sampling methods and the model based methods. For the strata, use as

an age cutoff 0-14, 15-35, 36+; use equal allocation and optimal allocation minimizing

variance.

You need to use R to analyze the data. The format of the project needs to be:

1. Analysis of NHANES data
