a. Explanation Given: The back-to-back stem plot is: Here, it is given that 4|2 shows the 420-429 represents. Thus, it could be said that 5|5 shows the 550-559 hours. The longest time of the battery is shown by the bottom of the provided plot. Thus, the longest that any battery is lasting is 550-559 hours. b. To determine To provide: The reason to prefer the battery X. Explanation The battery X might be preferred because its minimum life is 300 hours which is greater than the minimum battery life of 170 hours for battery Y. c. To determine To provide: The reason to prefer the battery Y. Explanation The brand of battery Y might be preferred because it has the greater lifetime in comparison of the batteries of brand X.
