Let Y be a random variable. Suppose you are interested in estimating the population mean, E(Y). Which of the following statements about confidence intervals and hypotheses tests are true? (Check all that apply.) A. A single hypothesis test about the population mean, E(Y), contains more information than a confidence interval. B. A confidence interval summarizes the set of hypotheses about the population mean, E(Y), you can and cannot reject at a given significance level. C. A confidence interval defines a rejection rule, at a specified significance level, for all possible values of the population mean, E(Y), whereas a single hypothesis test is a rejection rule for only one possible value of the population mean. D. A confidence interval defines a rejection rule, at a specified significance level, for only one possible value of the population mean, E(Y), whereas a single hypothesis test is a rejection rule for all possible values of the population mean.

Option (c) is correct.

The complete factored form of her polynomial is

Step-by-step explanation:

Given :  Pascha is factoring the polynomial, which has four terms.

is factored as  

We are required to choose the completely factored form of her polynomial from the given options.

Factored form of a polynomial is writing the polynomial in the smallest form so that when we multiply we get the same original  polynomial.

Consider

Taking (x-5) common from both terms , we get,

Thus, we obtained

Hence, option (c) is correct.

The complete factored form of her polynomial is
