Can you me solve this question? cara has a list of all 720 students in her middle school. she write the name of each student on a slip of paper and put each slip in a box. then she pulls 30 names from the box to decide who she will survey about the upcoming school election.

question

what are different attributes of students or different groups of students that should be represented in the sample?

randomly select 10. Listen to Persian music

Step-by-step explanation:

Just listen to Aron Afshar.

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.
