AlgebraQ&A Library4. A study conducted in the early 1960's in 9 counties in northern Oregon and southern Washington related exposure to the Hanford Mortality Exposure nuclear plant and mortality rate. Exposure is an index number 147.1 2.5 130.1 2.6 assigned to a county based on its population and proximity to the 3.4 129.9 contaminated water. Mortality is the rate of deaths per 100,000 1.3 113.5 man-years (6 people living for 70 years is 6x70-420 man-years). 1.6 137.5 3.8 162.3 11.6 207.5 Make a graph of the data (use graph paper, label completely, a) 6.4 177.9 and choose the correct axis for the independent(x) and 8.3 210.3 dependent(y) variables). Find the slope between the lowest and highest exposure counties, accurate to 2 decimal b) places. Add a trend line to the graph. c) Choose two representative points from your trend line and find the slope. Explain the d) meaning of the slope in context. Estimate the y-intercept and explain its meaning in context. e)Question

Please explain the solution which you will provide in detail. Concentrate on D and E more
