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.

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
Table 3
336
363

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.
