4. The Median Now that you have had some experience with cost functions, try minimizing the expectation value of this cost function: x-i. This is not as nice, since there is an absolute value, which is discontinuous. Show that the result of minimizing the expected value of fx- with respect to your estimate is the median. Hint: Break the integral into two pieces using the definition of the absolute value Hint 2: You don't have to show that one-half of...

NOW you should try these steps on the reaction between magnesium metal and hydrochloric acid. 1. Write the balanced molecular equation for the reaction. This reaction is a single replacement (metal + acid), so you should be able to predict what the products of the reaction are. 2. Now look at each specie in your equation and write them as they actually exist. Refer back to parts 1-4 of this exercise as necessary. This will be your total ionic equation:...

3. You will have just a single observation of X on which to base your choice between Ho: X has a Normal distribution with mean u = 5 and standard deviation o = 2 а VS. H1:X has a Binomial distribution with n =25 and p = 0.20. Consider the rejection rule "Reject Ho if X is an integer" Find a P(Type I Error) and B = P(Type II Error). Justify your answer.

Okay, now for some fun. The following equations will require that you add some molecules to complete them. For instance, in aqueous solution you can always add water, H or OH to help you balance the equation. As a tip, never try balancing oxygen first (that can lead to all kinds of trouble), instead start with cations and polyatomic ions, then consider hydrogen/protium, and then consider water and oxygens. For some of these reactions, you may also need to consider...

You
are constructing a circuit in your predecessor’s notes to try to
verify some of their results. The circuit in their notes shows a
copper wire with diameter of 0.5 mm, but you only have aluminum
that you can draw to any diameter you need (see
https://www.youtube.com/watch?v=Q2l6r6751IM). What diameter should
you specify to production staff to get the resistance that you need
over the same length in the circuit?
