Question-2 a. A dynamic cone penetrometer DCP is used for measuring material resistance to penetration (mm/blow) as a cone is driven into pavement. A sample of size 52 for DCP values in pavement structure evaluation has a mean of 28.7615 and a standard deviation of 12.2647. Test that the true = average DCP value, μ 30 against that the true average DCP value, μ< 30 using level of significance of 0.02.
