Based on data from two very large independent samples, two students tested a hypothesis about equality of population means using α = 0.02. one student used a one-tail test and rejected the null hypothesis, but the other used a two-tail test and failed to reject the null. which of these might have been their calculated value of t?

Recall the definition of a polynomial expression. find two polynomial expressions whose quotient, when simplified, is. use that division problem to determine whether polynomials are closed under division. then describe how theother three operations-addition, subtraction, and multiplication-are different from division of polynomials.
