1)D,since the 25th value is 5 and 26th value is 6 so the median is (5+6)/2 = 5.5
2) Greater than 5 hours=25

So the ratio is 3:1

For greater than 5 hours the number should be 15 right, cause for less than 4 hours we are taking 5 hours only then why not the same in case of less than 5 hours?

samarpan.g28 · Answer

For greater than 5 hours we are adding 15+6+3+1 = 25 people. For less than 4 hours we are adding 2+3 = 5 people. Therefore, the ratio becomes 25/5 = 5:1.

cheshire · Answer

Median is the mid point in data, you take the least data point (2) and the greatest data point (9) and average them: 5.5

cheshire · Answer

You add up all the y values past 5 on the x axis and compare it to all the y values added up below 4 on the x axis. That gives you a ratio of 25:5 or 5:1

shubhamsomani020 · Answer

<= 4 are 15, >= 7 are 10 so take 5 rom 6 , now 10 are from 5 and 10 from 6 so therefore 5.5

svsivakrishna · Answer

Question 1: The given number of hours spent are 2,3,4,5,6,7,8,9

Therefore median = (5+6)/2 = 5.5

svsivakrishna · Answer

Question 2:

Total for greater than 5 hours means-  either 6,7 ,8 & 9 hours, sum of which is 15+6+3+1 = 25;

Total for less than 4 hours means -  either 2 or 3 hours sum of which is 2+3= 5

ratio is therefore 5:1
