For each probability and percentile problem, draw the picture. Suppose that the useful life of a particular car battery, measured in months, decays with parameter 0.025. We are interested in the life of the battery. Part (a) In words, define the Random Variable X. O the life, in years, of a car battery the life, in months, of a car battery the number of batteries that last a lifetime the number of car batteries that an individual needs to replace Part (b) Is X continuous or discrete? continuous discrete Part (c) Give the distribution of X. X - U 0.02 Part (d) On average, how long would you expect one car battery to last? 50 months Part (e) On average, how long would you expect 5 car batteries to last, if they are used one after another? 250 months Part (f)webassign.net + 88 Topic: 10.7 Discussion--Rising Savings during the Pandemic Hmwk: Chapter 5 x F21 MATH DO10 Introductory Statistics 51Z Shukla 01505, Fall 2021 | We... the number of car batteries that an individual needs to replace Part (b) Is X continuous or discrete? continuous discrete Part (c) Give the distrib X ~ U 0.02 Part (d) On average, how long would you expect one car battery to last? 50 months Part (e) On average, how long would you expect 5 car batteries to last, if they are used one after another? 250 months Part (f) Find the probability that a car battery lasts more than 39 months. (Round your answer to four decimal places.) 0.3772 Part (9) 80% of the batteries last at least how long? (Round your answer to two decimal places.) 11.16 months Viewing Saved Work Revert to Last Response
