Question 4 (2 points): Three different models of rechargeable batteries are being considered for a remote wireless network application. Each of the three batteries have Weibull-distributed times to failure with a

characteristic life of 10,000 hours. However, model A has a shape factor of 1.2, model B has a shape factor of 2.8, and model C has a shape factor of 4.3. Plot the predicted reliability as a function of time for these three battery models, and explain the relative merits of each choice.
