Suppose you found an estimate of a parameter by setting the derivative of the log-likelihood equal to 0 and solving the equation. Give examples of two situations where this is this not the maximum likelihood estimate. (There are at least 4 possibilities, you only need to mention two.)

You do not need to reference specific distributions or numbers, just features/shapes of the likelihood. Please limit your answer to 2 or 3 sentences total, preferably 1.

Assignment No. 3.4 PROBLEM: Suppose you are the administrator in charge of setting the toll for crossing a toll bridge across a river. The current toll is $1 per trip and at that toll 1000 trips per hour are taken across the bridge. (a) If the price elasticity of demand for trips is 2.0, what will happen to the number of trips taken per hour if you raise the toll by 10 percent? How would this affect the total revenue...

6.45 Fuel efficiency in metric units. In the previous exercise, you found an estimate with a margin of error for the average miles per gallon. Convert your estimate and margin of error to the metric units kilometers per liter (kpl). To change mpg to kpl, use the fact that 1 mile = 1.609 kilometers and 1 gallon = 3.785 liters. 6.44 Fuel efficiency. Computers in some vehicles calculate various quantities related to performance. One of these is the fuel efficiency,...

Suppose that you performed a Simple Linear Regression of Height (equal the y-variable) on Weight (equal the x-variable). If the calculated r-value was equal to 0.9575, which of the following statements are appropriate parts of the interpretation of this r-value? Choose ALL that apply. A. Given that the r-value is 0.9575, the r-squared value will be 0.9785, rounded off to the 4th decimal place. B. Since this r-value is a positive number, the estimated y-intercept will also be a positive...

Suppose you work for an insurance company. You know that there are equal numbers of individuals who will get in an accident with probability 0.2 and 0.3 and that the loss from getting in an accident is $4,000. Suppose you wish to screen individuals by offering full- coverage insurance as well as 30 percent coinsurance (i.e., the insurance pays 30 percent of the loss amount, or $1,200, in the event of an accident). You wish to include a 5 percent...
