The average use, per year, of the cobot is 4.5 hours per day, 6 days per week, for 48 weeks. The battery selected for use in the Cobot has demonstrated a Weibull failure pattern with a decreasing failure rate characterized by a shape parameter of 0.5 and a scale parameter of 190,082 hours. a. Compute the reliability of the cobot's battery for one year of average use. b. Given the battery survives for one year of average use, what is the reliability at the end of the second year of average use
