A researcher creates two random samples, each with a sample size of 8. He does not find a statistically significant difference between the two groups.
Which of the following statements is correct? Select all that apply.
A. Since random samples were used, the conclusion is likely to be
true.
B. Increasing or decreasing sample size does not impact the
outcome of a statistical analysis.
c. Since the sample size of each group is greater than 5, the
conclusion is likely to be true.
D. Since the sample size is so small, the conclusion is likely to be
untrue

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

y/x of point b= y/x of point a

(i got the same question, this was the correct answer.)
