3. Plastics are becoming an extreme source of environmental pollution world- wide. Bioengineers isolated bacteria capable of using plastic as a major carbon source. Here is the amount of weight lost over time from a (SO-mg piece of plastic placed in a solution containing the new bacteria: Time daysx D 7 14 17 21 28 42 56 70 Weightlost mg y 2 6 11 13 17 25 31 42 52 n = 9; 2.1: = 255; 21:2 = 11559; 2y = 199; )3 y: = 5573; :3 my = 8768;. = 23275523,, = 15.35559. Answer the following questions: (a) Plot an appropriate graph for the data. Briey comment. (b) What is the main function of the best linear prediction equation? (c) Compute the best linear prediction equation: 1'; = a + bx. Use any valid method. (d) For every additional day, by how much is the weight lost, on average? (e) Predict the weight lost in a 90-day length of period. Are you bothered or not by this prediction? Briefly explain. (f ) Give the value of the statistic that measures the linear association between weight loss and time, and briey interpret. Use any method for the calculation. (3) What is your overall judgment about the linear t
