Suppose we have the following Boolean function f:B^3 ==> B where f(x, y, z) = x(y + z). How can we determine the domain and range of this function?
**Weegy:** We write f : A ? B to indicate that f is a function from A to B. We call the set A ... f. To specify a function completely you must give its domain, range and rule. ... [ Notice that we have used p, q and r for variables instead of x, y and z, which are ... h : ×3{0,1}?{0,1}, there are two possible choices that we could assign to h(p, q, r) for. ] (More)

What is the definition of algebra of logic and algebra of set theory? **Weegy:** Mathematical logic (also symbolic logic, formal logic, or, less frequently, modern logic) is a subfield of mathematics with close connections to the foundations of mathematics, [ theoretical computer science and philosophical logic.[1] The field includes both the mathematical study of logic and the applications of formal logic to other areas of mathematics. The unifying themes in mathematical logic include the study of the expressive power of formal systems and the deductive power of formal proof systems. The algebra of sets develops and describes the basic properties and laws of sets, the set-theoretic operations of union, intersection, and complementation and the relations of set equality and set inclusion. It also provides systematic procedures for evaluating expressions, and performing calculations, involving these operations and relations. ] (More)

What does the letter t represent in the following: t(58) = 2.001, p
test statistic
t-value
degrees of freedom
significance level
**Weegy:** Answer:
t-statistic
In statistics, the t-statistic is a ratio of the departure of an estimated parameter from its notional value and its standard error. [ It is used in hypothesis testing, for example in the Student’s t-test, in the augmented Dickey–Fuller test, and in bootstrapping.
t-statistic for this parameter is any quantity of the form
Most frequently, t-statistics are used in Student's t-tests, a form of statistical hypothesis testing, and in the computation of certain confidence intervals.
The key property of the t-statistic is that it is a pivotal quantity – while defined in terms of the sample mean, its sampling distribution does not depend on the sample parameters, and thus it can be used regardless of what these may be.
