Problem 6E

A person gets on and off a bathroom scale four times. The four readings (in pounds) are 148, 151, 150, and 152. Each time after the person gets off the scale, the reading is 2 lb.

a. Is it possible to estimate the uncertainty in these measurements? If so, estimate it. If not, explain why not.

b. Is it possible to estimate the bias in these measurements? If so, estimate it. If not, explain why not.

Answer

Step 1 of 3

The given information is when the person gets on the scale the for four times

the readings are 148,151,150,152

When the person gets off from the scale the reading is 2lb

Yes we can find the uncertainty in the given measurements

Find the mean and standard deviation of the measurements
