Answer 2

Answer:

i) The mean's formula=Sum of observations/ Number of observations.

So, Add all the numbers and divide it by the number of numbers.

For this question the answer is 40.4.

ii)Mode is the observation which is repeated for the highest number of times in the given set of numbers.

So, In this question the mode is 38 and 43.

Median is the middle-most number in the set of observations given. If we have an even number of observations you can just use this formula( number of observations +1/2)

So, in this question the median is 43.

iii)yes because both the numbers are repeated the equal number of times.
