7,900 chairs per months if production lowered by 6% find the new number of chairs produced each month

To get 6%, the easiest way I have found is to multiply the total number by the decimal form of the percentage and then subtract that from the total:

7900 x 0.06= 474

7900-474= 7426 per month.

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.
