A security analyst has regressed the monthly returns on Exxon Mobil equity shares over the past five years against those on theStandard & Poor's 500 stock index over the same period. The resulting regression equation is TEM= 0.09 +0.81rSp. Use this equationand any other information you deem appropriate to estimate Exxon Mobil's equity beta. (Round your answer to 2 decimal places.)Estimated Exxon Mobil's equity betac

Develop a scatterplot and explore the correlation between customer age and net sales by each type of customer (regular/promotion). Use the horizontal axis for the customer age to graph. Find the linear regression line that models the data by each type of customer. Round the rate of changes (slopes) to two decimal places and interpret them in terms of the relation between the change in age and the change in net sales. What can you conclude? Hint: Rate of Change = Vertical Change / Horizontal Change = Change in y / Change in x
