Question
The research hypothesis posits that the treatment will result in an outcome greater than zero
(H1: rxy > 0.) What would be concluded for r(29) = .467, p < .05?
a. The obtained value (.467) is greater than the critical value (.296) so it can be concluded that the relationship between the two variables occurred by something other than chance. The research hypothesis, which posits a positive relationship between the variables, is supported.
b. The obtained value (.467) is less than the critical value (.296) so it can be concluded that the relationship between the two variables did not occur by something other than chance. The research hypothesis, which posits a positive relationship between the variables, is not supported.
c. Their relationship is zero.
d. The obtained value (-.467) is greater than the critical value (22.96) so it can be concluded that the relationship between the two variables occurred by something other than chance. The research hypothesis, which posits a positive relationship between the variables, is supported.
Explanation / Answer
Ans:
H0:r=0
H1:r>0
As,p-value<0.05,we reject null hypothesis.
or critical r value(one tailed,0.05)=0.296
Option a is correct.
The obtained value (.467) is greater than the critical value (.296) so it can be concluded that the relationship between the two variables occurred by something other than chance. The research hypothesis, which posits a positive relationship between the variables, is supported.
