A presidential candidate's aide estimates that, among all college students, the proportion p who intend to vote in the upcoming election is at most 75%. If 221 out of a random sample of 270 college students expressed an intent to vote, can the aide's estimate be rejected at the 0.01 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table. (If necessary, consult a list of formulas.) (a) State the null hypothesis H and the alternative hypothesis H,. H, :0 H, :0 (b) Determine the type of test statistic to use. D=0 OSO (c) Find the value of the test statistic. (Round three or more decimal places.) O

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
