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, 116, 122, 110, 175, 126, 125,
111, 118, 117.
Calculate: Sample Mean, Sample Median, 20% trimmed Mean,
Quartiles: Q1, Q2 and Q3
Interquartile range: IQR = Q3 –Q1 , Lower bound = Q1 - 1.5(Q3
- Q1), Upper bound = Q3 + 1.5(Q3 - Q1).
Maximum, Minimum, Range = Max...
