A least-squares curve fit of the data in the table x= 1,3,4,6 and y= 2,3,4,5 led to a best straight line with the equation y = 0.615x 1.35
(a) If the y value of a new measurement is 3.24, what are the corresponding x value and the uncertainty in the x value? [The uncertainty in y (sy) is 0.196.]
x value = 3.07
uncertainty = +/- ?
(b) Suppose y was measured five times and average of these five measurements was 3.24. What is the uncertainty in x based on these five measurements?
