The article "measurement of complex permittivity of asphalt paving materials" (j. shang, j. umana, et al., journal of transportation engineering, 1999: 347– 356) compared the dielectric constants between two types of asphalt, hl3 and hl8, commonly used in pavements. for 42 specimens of hl3 asphalt the average dielectric constant was 5.92 with a standard deviation of 0.15, and for 37 specimens of hl8 asphalt the navidi-3810214 book november 11, 2013 14: 8 432 chapter 6 hypothesis testing average dielectric constant was 6.05 with a standard deviation of 0.16. can you conclude that the mean dielectric constant differs between the two types of asphalt?
