- I am working on a project where I have data set of 30 households in the US, with the, marital status, income, number in household and annual expenditures on: food, fruits, meats, etc.. From this I need to run the appropriate method for estimating a parameter, based on a statistic (i.e., confidence interval method) The parameter i chose is food. I am having trouble coming up with an appropriate scenario for one parameter analysis.
