Question

A least-squares curve fit of the data in the table to the right led to a best straight line with the equation y = 0.615x + 1.35. If the y value of a new measurement is 3.67, what are the corresponding x value and the uncertainty in the x value? [The uncertainty in y (sy) is 0.196.] Enter all answers to the hundredths place. x value = uncertainty = plusminus Suppose y was measured five times and average of these five measurements was 3.67. What is the uncertainty in x based on these five measurements? plusminus

Explanation / Answer

a) x=3.772 uncertainty = 0.319
