Question: The article Permeability, Diffusion and Solubility of Gases (B. Flaconneche, et al., Oil and Gas Science and Technology, 2001:262278) reported on a study of the

The article €œPermeability, Diffusion and Solubility of Gases€ (B. Flaconneche, et al., Oil and Gas Science and Technology, 2001:262€“278) reported on a study of the effect of temperature and other factors on gas transport coefficients in semicrystalline polymers. The permeability coefficient (in 10^ˆ’6cm³(STP) /cm · s · MPa) of CO₂was measured for extruded medium-density polyethylene at both 60°C and 61°C. The results are as follows: 51 61 67 57 69 60°C: 54 51 60 63 62 60 66 66 68 61 60 61°C: 58 60

Find a 95% confidence interval for the difference in the permeability coefficent between 60—¦C and 61—¦C.

51 61 67 57 69 60C: 54 51 60 63 62 60 66 66 68 61 60 61C: 58 60
