A manufacturer of electronic components is interested indetermining the lifetime of a certain type of battery. A sample, inhours 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 – Min, Sample Variance, SampleStandard deviation. ? Stem and leaf, Dot plot.
