    The average breaking force of a certain type of fiber must be greater than 200 pounds per square inches (lppc). Previous experiments have shown that we can assume that the breaking force is normally distributed with a standard deviation σ = 4.5 lppc. A sample of 8 fibers gave the following breaking forces (in lppc): 210, 206, 198, 202, 201, 198, 199, 205. (a) Formulate a null hypothesis against alternative hypothesis to verify that this type of fiber is acceptable....
