47. Diving Scuba divers must know that the deeper the dive, the greater the water pressure in pounds per square inch
(psi) for fresh water diving, as shown in the diagram.
Can someone help me with 47. Please

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.

the correct answer is a.) bc< mn 5 stars if this you : )
