Question

determine the median of 24,23,a,a_1, 12,26,were a is the mean of 5,10,15,20,and 25​

Answer 1

Answer:

Median = 19

Step-by-step explanation:

Mean = a = Sum of observations/Number of Observations

= 5 + 10 + 15 + 20 + 25/5

= 1 + 2 + 3 + 4 + 5

= 15

So, a = 15

Therefore, the numbers are:

24, 23, 15, 14, 12, 26

In ascending order:

12, 14, 15, 23, 24, 26

Number of terms (N) = 6 which is even

For an even number of terms:

Median = ((N/2)th term + (N/2 + 1)th term)/2

= (15 + 23)/2

= 38/2

Ans = 19
