Requiredanswer:
The mean of score of two separate number of observations is given to us. We have to find the mean of both the sets.
GiveN:
Number of observations = 25
Mean score = 80
Total score of set 1 = 25 × 80 = 2000
Number of observations = 55
Mean score = 60
Total score of set 2 = 55 × 60 = 3300
Now from the above:
Total no. of obs. = 25 + 55 = 80
Total score = 2000 + 3300 = 5300
Formula for finding Mean:
\large{ \because{ \underline{ \boxed{ \rm{mean \: score= \frac{total \: score}{no. \: of \: observations} }}}}}∵
meanscore=
no.ofobservations
totalscore
Substituting the values,
⇛ Mean score = 5300 / 80
⇛ Mean score = 66.25 (Answer)
