Aperson 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. is it possible to estimate the uncertainty in these measurements? if so, estimate it. if not, explain why not. is it possible to estimate the bias in these measurements? if so, estimate it. if not, explain why not.

See explanation below

Step-by-step explanation:

Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of

148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25

We could estimate the uncertainty as the standard error SE

where  

s = standard deviation of the sample

n = 4 sample size.

Computing s:

So, the uncertainty is 1.479/2 = 0.736

It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight.

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road
