The breaking strengths of cables produced by a certain company are approximately normally distributed. The company announced that the mean breaking strength is 2120 pounds with a standard deviation of 180. A consumer protection agency claims that the actual standard deviation is higher.

State the null hypothesis H, and the alternative hypothesis H, they would use for this test. P Р Ho: O H₁: 0 O ê S OSO D>O CRO 0-0 040 5 1x b X < E
