1 30
2 29.5
3. 315
4. 28​

Answer 1

Answer:

median=29.5

Step-by-step explanation:

median means middle number.

even =n/2

odd=(n+1)/2

median of the data 28, 31, 42, 37, 26, 34, 18, 23,15.

ascending order: 15, 18, 23, 26, 28, 31, 34, 37, 42.

no of terms=9(odd)

=(9+1)/2

=10/2

=5th observation

=28

median= (8/2thobservation+(8/2+1)the observation)/2

median= (4th observation+ 5th observation)/2

median=(23+26)/2

=49/2

=29.5
