A manufacturer of electronic components is interested in determining the lifetime of a certain type of battery. A sample, in hours of life, is as follows: 123+x 116+x 122+x 110+x 175+x 126+x 125+x 111+x 116+x 117+x (where, x=your CGPA) i) Find the sample mean. ii) What feature in this data set is responsible for the substantial difference between the two values? Find the sample variance, standard deviation, and range. Using the calculated statistics in parts above, can you comment on the quality of the tires? iii) iv) A manufacturer of electronic components is interested in determining the lifetime of a certain type of battery.
