A hypothesis test was conducted with the following null and alternative hypothesis. The study did NOT provide enough statistical evidence to reject the null hypothesis. H 0: The true mean test score in a statistics class = .78
H A : The true mean test score in a statistics class > .78
Which of the follow statements is TRUE?

a. The p-value was less than the alpha and student showed higher test scores.
b. The p-value was greater than the alpha and student showed higher test scores.
c. The p-value was less than the alpha and student showed did not show higher test scores.
d. The p-value was greater than the alpha and student did not show higher test scores.

answer: y = -2.5x - 15

              (-6,0)

step-by-step explanation:

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.

86

step-by-step explanation:

find the area of the triangle then multiply by 2 then add the area of the parollelegram multiplied by 2
