A soccer ball is kicked at a velocity of 25 meters per second. The following table shows the horizontal distance (in meters) at different angles of elevation (in degrees), ignoring wind resistance. Angle of Elevation Distance Traveled 15 31.9 25 48.8 30 55.5 45 63.8 50 62.8 55 59.9 60 55.5 70 41.0 Using a graphing or online calculator, graph this set of data on a scatter plot for reference. Then, in two or more complete sentences, explain why a quadratic function should be used to model this set of data.

(b) suppose that consolidated power decides to use a level of significance of Ī± = .05, and suppose a random sample of 100 temperature readings is obtained. if the sample mean of the 100 temperature readings is xāÆāÆ = 60.990, test h0 versus ha and determine whether the power plant should be shut down and the cooling system repaired. perform the hypothesis test by using a critical value and a p-value. assume Ļ = 5. (round your z to 2 decimal places and p-value to 4 decimal places.)
