What sorts of follow up questions about the statistics might you ask that person in order to obtain the data needed to make a decision about the validity of that statement? in gerneral

Step-by-step explanation:

How was the data obtained?

Was the experiment controlled?

How large was the control group and the placebo group?

Was it a blind/double-blind test?

Were extreme outliers removed from the data before running the experiment?

Such questions can be asked to obtain a better understanding about the validity of the statement.

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.
