H0 shall be r = 0
Ha shall be r ≠ 0
Why because Tom is sceptical of Arron’s decision & Arron states presence of correlation.
If H0 is rejected it means there is correlation.
Hope this helps you!
As far as i know Ha can’t be equal
Yes you’re correct. Look at Aabhas’s ans.
Yes seems correct to me.
Aaron believes that there is a strong correlation. So to prove his significance-
H0: r= 0
H1: r ≠ 0
Since, T stat > T critical, we reject H0.
Then what should be the answer ?.
We should form alternate according to TOM or Arron ?
Aaron is the one who is arguing and it is his belief that there is a significant correlation between the two variables and not Tom’s belief . We have to check whether the statement made by Aaron is correct or not and for that we shall do the testing of correlation. So the answer is A.
