t = (dbar/sd )* sqrt(n)
t = -51.4286 /26.09506 *sqrt(7)= -5.21429
I have retained the accuracy and then rounded to 3 decimals
If we work with -51.4/26.1 * sqrt(7) then it will be -5.210
I am not quite sure how they feed the answer
If we consider differ (score after -score prior ) then t = 5.214
51.4/26.1 * sqrt(7) = 5.210
That is why I have provided all the possibilities
