A engineer picks 16 resistors at random and measures their resistance with an analog multimeter:

98.1, 99.3, 97.3, 98.2, 98.6, 97.3, 99.2, 98.3, 98.4, 97.9, 98.7, 97.4, 99.0, 99.1, 98.1, and 96.8 Ω

The resistor manufacturer reports that the “true” mean is 98.0 Ω.

a) Calculate the mean, sample standard deviation, and bias error in these measurements. Report the resistance measurement statistic in standard engineering form. No need to show individual steps for mean and standard deviation calculation.

b) Identify any outliers in the data set. You may use Excel but show your work and reasoning.
