Gretta slept for 180 hours and 23 minutes. Nat slept for 10,524 minutes. Who slept longer and by how much Gretta slept 4 hours and 59 minutes longer than Nat. Nat slept 4 hours and 59 minutes longer than Gretta. Gretta slept 22 hours and 36 minutes longer than Nat. Nat slept 22 hours and 36 minutes longer than Gretta.

where is the question I don't see a question

Gretta slept longer

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
