Question

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.

Researchers performed a study to address the question of whether
the mean body temperature of humans is 98.6 degrees °F.
Among other data, the researchers obtained the body
temperatures of 40 healthy humans, as provided in the accompanying
data table. 97.9, 97.5, 99.0, 98.1, 98.7, 98.8, 97.6, 98.5, 98.5,
98.8, 98.0, 98.2, 97.9, 98.0, 96.8, 97.4, 98.1, 98.0, 98.0, 98.7,
98.6, 98.8, 98.1, 97.0, 97.1, 97.2, 98.3, 97.7, 99.2, 97.8, 97.6,
97.8, 97.3, 98.0, 98.6, 98.5, 98.2, 97.0, 98.4, 98.8....
