In this assignment, you will investigate the relationship between test scores and other variables. First, you will see if the number of hours spent studying for a test affect the test score. Then you will see whether the number of hours slept the night before affect the test score. And finally, you will see if homework scores affect test scores. Once you determine the relationships that may be present, you can compare and interpret the trend lines for those relationships. Based on the description of the scenario, which of the variables is the dependent variable? Along which axis is the dependent variable traditionally plotted?

test score and y-axis

Step-by-step explanation:

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.
