The diameter of steel rods manufactured on two different extrusion machines is being investigated. The sample means are 8.69 cm and 8.51 cm and sample variances are 0.30 and 0.44, respectively from Machine 1 and Machine 2. If it is given that the population variances are not equal for both machines. Meanwhile the sample size for Machine 1 has been changed from 15 to 10. Construct the new confidence interval for difference between means diameter of steel rods manufactured by Machine 1 and Machine 2 at 95% level of significant.
