The article "measurement of complex permittivity of asphalt paving materials" (j. shang, j. umana, et al., journal of transportation engineering, 1999: 347β 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?
