You measure 50 watermelons' weights, and find they have a mean weight of 79 ounces. Assume the population standard deviation is 12.4 ounces. Based on this, construct a $ 99 \% $ confidence interval for the true population mean watermelon weight. Use $ z $ for the critical value. Give your answers as decimals, to two places $ \pm $ $ \square $ ounces

6. A parallel plate capacitor has circular plates of radius R and separation d << R. The potential difference V across the plates varies as V = Vo sin \omega t. Assume that the electric field between the plates is uniform and neglect edge effects and radiation. (a) Find the direction and magnitude of the magnetic induction B at point P which is at a distance r ($r < R$) from the axis of the capacitor. (b) Suppose you wish to measure the magnetic field B at the point P using a piece of wire and a sensitive high-impedance oscilloscope. Make a sketch of your experimental arrangement and estimate the signal detected by the oscilloscope.
