An emt must report to work at 2250 each day he is assigned to work. what does this mean in traditional time?

22:50 in military time converts to 10:50 PM

This is because 22 hundred hours is 10 PM

Subtract off 12 to convert from military time to regular time if the value is over 12, so 22 - 12 = 10. Anything over 12 is automatically PM (otherwise it's AM).

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.
