QUESTION 4 An electronic engineer in a manufacturing company is investigating two types of resistors. A random sample of 6 resistors from each type was installed in smart televisions. Each television was then applied with a high voltage of 300 volts causing damage to the electronic components The following are the cost of repairs (in RM): Resistor Type 1 Resistor Type 2 450 360 400 300 360 485 336 363 345 420 405 305 Table 3 Construct the 90% confidence interval (CI) for the mean cost of repairs using each type of resistor. State three (3) conditions for constructing the CI and give your observation from the confidence intervals.
