1. A sample of 20
bulbs each was picked from the manufacturing facility of two bulb manufacturers
— Mfr I and Mfr
2. The table above
provides the life of bulbs for the two manufacturers. You are a quality testing
person and are presented with this data:
i. Which manufacturer
has better performance on the life of bulbs? What are the different measures
you can consider to calculate performance?
ii. How would you
assess the variability in the performance of the two bulb manufacturers?
iii. Would your answer
to the first question change based on your assessment of the variability in the
performance of bulb manufacturers? (10 Marks)
2. For the data in the
table below: (10 Marks)
i. What do the
correlation coefficients of I, shaded in yellow, indicate?
ii. The highest
correlation coefficient is 0.84, shaded in green. What can you infer from that
score about the relationship between the two variables?
iii. The two lowest
correlation coefficients are 0.06 and -0.06. What can you infer from that score
about the relationship between the two variables?
