A chemical engineer for a tire manufacturer is investigating tire life for a new rubber compound andhas built 15 tires and tested them to end-of-life in a road test. The sample mean and standarddeviation are i = 60,139.7 ands = 3645.94 kilometers. Find a 99% confidence interval on the meantire life. Which t-distribution curve applies on the 99% confidence interval? Include your solution.O a. 57,336 sH S 62,914O d. 57,337 Su S 62,942t-2.947O b. NONEO. 57,337 sH S 62,94
