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.
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
