Hi I WOULD LIKE TO KNOW IF YOU CAN HELP ME TO DO THE ASSIGNMENT IN HEALTH STATISTICS THANKS
Random variables with zero correlation are not necessarily independent. Give a simple example.
Explain sampling bias and describe how random sampling serves to avoid bias in the process of data collection.
Suppose that your utility, U, is a function only of wealth, Y, and that U(Y) is as drawn below. In this graph, note that U(Y) increases linearly between points a and b.
Suppose further that you do not know whether or not you
Define the term Frequency Distributions?
In testing the null hypothesis H_{0}: P=0.6 vs the alternative H_{1} : P < 0.6 for a binomial model b(n,p), the rejection region of a test has the structure X ≤ c, where X is the number of successes in n trials. For each of the following tests, d
Kramer spends all of his income $270 on two products, soup (S) and on golf balls (G). He always bought 2 golf balls for every 1 cup of soup he consumes. He acquires no additional utility from the other cup of soup unless he as well gets 2 more golf balls a
