A sealed battery in an animal tracking tag has an average failure rate of 1 failure every 12 months. A team of biologists and conservation officials attached the tags to several wolves that were released into new territory.
a. What will be the reliability of the battery after three months?
b. Increased reliability through redundancy was suggested as a way to help improve the likelihood of being able to track the animals for a longer period of time. What are the pros and cons of that idea in this situation?
c. Suggest a remedy that might provide greater reliability-and thus longer tracking times-for the tag.
