A research center claims that at least 44% of adults in a certain country think the government is not aggressive enough in pursuing people who cheat on their taxes. In a random sample of 700 adults from that country, 38% say that the government is not aggressive enough in pursuing people who cheat on their taxes. At α=0.01, is there enough evidence to reject the center's claim? Complete parts (a) through (e) below. (b) Find the critical value(s) and identify the rejection region(s). The critical value(s) is/are z0= _____ (Round to two decimal places as needed. Use a comma to separate answers as needed.) What is/are the rejection region(s)? Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to two decimal places as needed.) A. z> ____ B. z< ____ C. z<____ and z > ____ (c) Find the standardized test statistic z. z= (Round to two decimal places as needed.)
Optimization
Optimization comes from the same root as "optimal". "Optimal" means the highest. When you do the optimization process, that is when you are "making it best" to maximize everything and to achieve optimal results, a set of parameters is the base for the selection of the best element for a given system.
Integration
Integration means to sum the things. In mathematics, it is the branch of Calculus which is used to find the area under the curve. The operation subtraction is the inverse of addition, division is the inverse of multiplication. In the same way, integration and differentiation are inverse operators. Differential equations give a relation between a function and its derivative.
Application of Integration
In mathematics, the process of integration is used to compute complex area related problems. With the application of integration, solving area related problems, whether they are a curve, or a curve between lines, can be done easily.
Volume
In mathematics, we describe the term volume as a quantity that can express the total space that an object occupies at any point in time. Usually, volumes can only be calculated for 3-dimensional objects. By 3-dimensional or 3D objects, we mean objects that have length, breadth, and height (or depth).
Area
Area refers to the amount of space a figure encloses and the number of square units that cover a shape. It is two-dimensional and is measured in square units.
