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 variance of 35,156.25. A consumer protection agency claims that the actual variance is higher. Suppose that the consumer agency wants to carry out a hypothesis test to see if its claim can be supported. State the null hypothesis H and the alternative hypothesis H, they would use for this test.
