Question

The 95 % confidence interval for the difference between two related population means is a given:

(X - X) - T (S) TO (X - X ) +T (S)

1 2. 0.5 1 2. 0.5

-----------------------------------------------

(X - X) - T (S-d) TO (X - X ) +T (S-d)

1 2.   0.95 1 2. 0.95

------------------------------------------

(X - X) - T (S-d) TO (X - X ) +T (S-d)

1 2 0.5     1 2   0.5

-------------------------------------------

(X - X) - T (S-D) TO (X - X ) +T (S-d)

1 2  0.95 1 2.   0.95

Answer 1

Please don't hesitate to give a "thumbs up" in case you're satisfied with the answer

The correction option is basically the option number 3.

(X - X) - T (S-D) TO (X - X ) +T (S-D)

1 2  0.95 1 2.   0.95

Because S-D is he correct notation , and also 95% is the CI that is asked in the question.
