Consider the following table summarizing the speed limit of a certain road and the number of accidents occurring on that road in January. Posted Speed Limit 55 47 42 35 21 22 Reported Number of Accidents 28 22 23 16 17 11 1. Find the slope of the regression line predicting the number of accidents from the posted speed limit. Round to 3 decimal places. 2. Find the intercept of the regression line predicting the number of accidents from the posted speed limit. Round to 3 decimal places. 3. Predict the number of reported accidents for a posted speed limit of 42 mph. Do not round the slope and intercept in doing the calculation. Round to the nearest whole number
