Answer 2

Answer:

Here is your answer please make me brainliest and follow me

Step-by-step explanation:

Arranging the given data in ascending order, we get

127,139,139,140,142,145,150,152,153,155

Total number of observations = n = 10 which is even .

$median = \frac{ \frac{n}{2}th \: observation \: + ( \frac{n}{2} + 1) \: th \: observtion }{2} \\ = \frac{5 \: th \: observatio \: + 6 \: th \: observation}{2} \ \\ \\ = \frac{142 + 145}{2} \\ \\ \frac{287}{2} = 143.5 \: \: ans......$
