The number of newly reported crime cases in a county in New York State is shown in the accompanying table, where x represents the number of years since 2003, and y
represents number of new cases. Write the linear regression equation that represents
this set of data, rounding all coefficients to the nearest hundredth. Using this
equation, estimate the calendar year in which the number of new cases would reach
670.

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.

okay wait before i answer, is this for your points on a graph?

hi there!

the answer will be d: 2

dont trust me im no expert these losers made me fail a test bro this sucks
