The density curve for a continuous random variable X has which of the following properties?

(A) All of the answer options are correct.
(B) The total area under the density curve for X must be exactly

(1) The probability of any event of the form X = constant is 0. The probability of any event is the area under the density curve and above the values of X that make up the event.

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.
