Special Rounding Instructions When you perform logistic regression, round the r value to three decimal places and the other parameters to two decimal places. Round all answers to two decimal places unless other-wise indicated.

Fluorescent Bulbs Compact fluorescent light bulbs save energy when compared with traditional incandescent bulbs. Our green energy campaign includes efforts to get local residents to exchange their incandescent bulbs fur fluorescent bulbs. Initially $200$ households make the change. Market studies suggest that, in the absence of limiting factors, we could increase that number by $25\%$ each month. In our target area, there are $250,000$ households, which we take as the limiting value. Make a logistic model that gives the number of households converting to fluorescent bulbs after t months.
