g Using the previous part, find confidence intervals for α with asymptotic level 90% using both the "solving" and the "plug-in" methods. Use n=25 , and X¯¯¯¯n=4.5 . (Enter your answers accurate to 2 decimal places. Use the Gaussian estimate q0.05≈1.6448 for best results.)

Explain why the function is discontinuous at the given number a. (select all that apply.) f(x) = 1 x + 1 a = −1 f(−1) is undefined. lim x→−1+ f(x) and lim x→−1− f(x) exist, but are not equal. lim x→−1 f(x) does not exist. f(−1) and lim x→−1 f(x) exist, but are not equal. none of the above

Solve the given system of equations. 2y= -x+9 , 3x-6= -15

Two students were asked if they liked to read. is this a good example of a statistical question? why or why not? a yes, this is a good statistical question because a variety of answers are given. b yes, this is a good statistical question because there are not a variety of answers that could be given. c no, this is not a good statistical question because there are not a variety of answers that could be given. no, this is not a good statistical question because there are a variety of answers that could be given
