Purebred dogs are first assigned the same litter number until they are individually registered with a name. then the dogs will be assigned a unique registration number with a dog registry. many people choose to have a microchip implanted in the dog so that it can be read to immediately find the dog's owner.
which of the following relations is not a function? (2 points)
(registration number, litter number)
(microchip number, registration number)
(litter number, microchip number)
(microchip number, litter number)

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.
