The breaking strengths of cables produced by a certain company are approximately normally distributed. The company announced that the mean breaking strength is 2140 pounds with a variance of 32,761. 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 Ho and the alternative hypothesis H₁ they would use for this test. Ho: O H₁:0 μ 0 020

The breaking strengths of cables produced by a certain company are approximately normally distributed. The
company announced that the mean breaking strength is 2140 pounds with a variance of 32,761. 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 Ho and the
alternative hypothesis H₁ they would use for this test.
