2) We saw in class that under certain conditions it can be shown that 7 is BLUE for My. State what the letters B and U in BLUE stand for and define them fully for full credit. (I will do L for you as an example: “The letter L stands for Linear. This means that the estimator is a weighted average of Y;, i = 1,.., n.”) Now tell me what B and U stand for and define them fully....

In class, we analyzed Buffon's needle experiment. We showed that if a large sheet of paper has parallel lines that are 1 inch apart, and we throw a needle of length 1/2 inch at it, the probability that the needle hits a line is l/r. We can estimate π by throwing many needles and seeing how many throws hit a line. Suppose we throw a needle n times, and each throw is independent. Let X be the number of throws...

This C++ Program consists of: operator overloading, as well as experience with managing dynamic memory allocation inside a class. Task One common limitation of programming languages is that the built-in types are limited to smaller finite ranges of storage. For instance, the built-in int type in C++ is 4 bytes in most systems today, allowing for about 4 billion different numbers. The regular int splits this range between positive and negative numbers, but even an unsigned int (assuming 4 bytes)...
