Alpha true and false Which of the following statements are true? If false, explain briefly.
a) Using an alpha level of 0.05, a P-value of 0.04 results in rejecting the null hypothesis.
b) The alpha level depends on the sample size.

c) With an alpha level of 0.01, a P-value of 0.10 results in rejecting the null hypothesis.
d) Using an alpha level of 0.05. a P-value of 0.06 means the null hypothesis is true.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road

it is c!

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
