Problem A. standard deviatiol 1oolb. By a few techniques in the manufacturing process, it is claimed that the breaking strength can be increased. To test the claim, a sample of 50 cables is tested, and it is found that the mean breaking strength is 1850lb. FThe breaking strengths of cables produced by a manufacturer have mean 1800 lb and a 1. What will be the appropriate test direction of the alternative hypothesis? C. nondirectional A. one-sided, to the left of hypothesized value B. one-sided, to the right of the hypothesized value D. cannot be determined What will be the hypothesized value? A. 1800 В. 1850 С. 100 D. 50
