    Answer:

    Seema obtained the following scores (out of 100) on a set of spelling tests:

    80, 85,90,71,60,100. What is her mean score?​

    Sol-: Scores obtained by Seema = 80, 85,90,71,60,100.

           Thus, mean = sum of all observations/number of observations

            ∴ 80 + 85 + 90 + 71 + 60 + 100/6

            = 486/6

            = 81 Ans.

    Therefore, her mean score = 81 Ans.
