1) (5) Ratio estimation and related methods can be used for early prediction of election returns. The data below, posted on Bb, are rom 10 Florida counties. For county 1, Xi = number of votes cast for the Mparty candidate (Perot) in 1996 y; = number of votes cast for the m party candidate (Buchanan) in 2000 Assume that this data is a simple random sample from the N = 6'? Florida counties. You are also given that T): = 483,??6 Li- there were this many total votes cast for Perot in 1996 over all 67 counties. Make a scatter plot of the data and comment on whether ratio estimation seems appropriate here. Make sure that the origin (x=0, y=0) is included in your plot.

Interpret this in plain language based on these results, what was Buchanan's Florida popularity in 2000 as compared to Perot's in 1999 ? 3) (5) Estimate Ty with error bound. 4) (5) If we treated these ten counties as a pilot sample, use the information here to calculate a sample size n so that we may estimate 1,. with an error bound of 1000 votes
