A basketball coach plotted data about her shooting guard’s playing time and point scoring in a scatterplot. Shooting Guard Minutes Played and Points Scored Which is the equation of the line of best-fit? y = StartFraction 15 Over 22 EndFraction x + StartFraction 6 Over 11 EndFraction
y = StartFraction 15 Over 22 EndFraction x + StartFraction 43 Over 11 EndFraction
y = StartFraction 22 Over 15 EndFraction x minus StartFraction 86 Over 15 EndFraction
y = StartFraction 22 Over 15 EndFraction x minus four-fifths

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.
