6.24 An industry pays an average wage rate of $9.00 per hour. A sample of 36 workers from one company showed a mean wage of $8.50 and a sample standard deviation of $0.60. But a general perception is that the true or population standard deviation is above $0.58. Test using a 5% level of significance whether the sample evidence is significant to justify the general perception. Assume that the sample is from a normal population.
