Q 5. Tropical Cable Limited has different types of electrical cable insulation. Two of which have been tested recently by RMU students to determine the voltage level at which failures tend to occur. When the specimens were subjected to an increasing voltage stress in a laboratory experiment, failures for the two types of cable insulation occurred at the following voltages: Insulation Type A 236, 245, 244, 249, 241, 237, 253, 241, 238, 244, 236, 235, 234, 244 Insulation Type B 260, 255, 264, 254, 238, 248, 258, 246, 266, 270, 252, 262 Determine ninety-five percent (95%) confidence interval estimates for the difference in the population means and variances of the two types of insulation types. State any assumptions you made to enable you answer this
