A wildlife management team studied the reproduction rates of deer in three tracts of a wildlife preserve. The team recorded the number of females x in each tract and the percent of females y in each tract that had offspring the following year. The table shows the results. Number, x 100 120 140 Percent, y 75 68 55 1. Find the least squares regression line for the data. 2. Use the model to create a table of estimated values for 3. Compare the estimated values with the actual data. 4. Use the model to estimate the percent of females that had offspring when there were 170 females 5. (e) Use the model to estimate the number of females when 40% of the females had offspring.
