10. A chemist has developed a new synthetic fiber. To measure the fiber's strength, experiments are performed on ten strands of this fiber to determine the average number of pounds that can be supported by strands of this fiber before breaking. The following breaking-load results (in pounds) were obtained: 3.3 2.2 3.1 2.8 2.6 2.9 3.0 2.4 2.7 3.2 Construct a 95% confidence interval for the mean breaking strength of a strand of this new fiber.
