Ahypothesis test with a sample of n = 25 participants produces a t statistic of t = +2.53. assuming a one-tailed test with the critical region in the right-hand tail, what is the correct decision? (a) the researcher can reject the null hypothesis with a = .05 but not with a = .01.(b) the researcher can reject the null hypothesis with either a = .05 or a = .01.(c) the researcher must fail to reject the null hypothesis with either a = .05 or a = .01.(d) it is impossible to make a decision about h0 without more information.

Option B is right.

Step-by-step explanation:

Given that a hypothesis test with a sample of n = 25 participants produces a t statistic of t = +2.53.

df = 24

p value = 0.009191

Since p value is less than 0.01 , we reject null hypothesis at 1%, 5% and 10% significance level.

(B) The researcher can reject the null hypothesis with either a = .05 or a = .01

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
