Scenario 2: The breaking strength of cables produced by a manufacturer have a mean of 1800 lb and a standard deviation of 100 lb. By a new technique in the manufacturing process, it is claimed that the breaking strength can be increased. To test this claim, a sample of 50 cables is tested and it is found that the mean breaking strength is 1850 lb. Test if this data can support the claim at 1% level of significance. Test the hypothesis in the given situation. Follow the steps in hypothesis testing and draw a conclusion. Write the null and alternative hypothesis in sentence form and in symbols. Shade the rejection region in the normal curve. Write the conclusion in statement form.
