3. Here is a calculation 5-(-11)
(a) Figure out the answer to the calculation:
(b) Which of these story questions fits the calculation? Circle any that apply.
A
It was extremely cold at midnight.
During the morning, the temperature rose by 5°C
By midday. It had reached - 11°C
What was the temperature at midnight?
B
The temperature at midnight was -11°C
By midday, the temperature was 5°C
What was the temperature change?
C
At midday. the temperature was 5°C.
The temperature then fell by 11°C
What was the final temperature?
Explain your answer.

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.

351°f
