Answer 1

Answer:

30

Step-by-step explanation:

Since we have given that

Number of observation = 10

Mean = 25.6

So, Sum of observations is given by

25.6\times 10=25625.6×10=256

Including 1 observation, the mean is 26.

So, Sum of observations is given by

26\times 11=28626×11=286

So, the value of newly included observations is given by

286-256=30286−256=30

Hence, the newly included observation is 30.
