d) Find a 99% confidence interval for the mean sales of the lens when sales of the camera body are 150 and the price of the lens is $700. Provide an explanation of the meaning of this interval.

e) Find a 99% prediction interval for the sales of the lens when sales of the camera body are 150 and the price of the lens is $700. Explain its meaning relative to the problem. Compare the width of this interval to that of the interval calculated in the previous part of the problem. Give a reason for any difference in the width of this interval and the one you found in the previous part of the problem.

An alpha-particle has a charge of +2e and a mass of 6.64 * 10^-27 kg. It is accelerated from rest through a potential difference that has a value of 1.10 * 10^6 V and then enters a uniform magnetic field whose magnitude is 2.80 T. The alpha-particle moves perpendicular to the magnetic field at all t...

Recall how we saw in class that if we add a total time derivative of a function g(g; t) on configuration space to the Lagrangian then the equations of motion were unaffected, i.e. the new Lagrangian gives the same Euler-Lagrange equations as the original Lagrangian L. The reason this worked was that...
