Ответ:
The median of Group A is greater than the median of Group B.
Step-by-step explanation:
Given
Required
Which of the options is true
(a) Group A complete in less time
To do this, we calculate the average of both using:
Where
So, we have:
The average time of Group A is higher than that of B, this means that Group A spend more time, on average.
(b) Group A has a greater median
First, we sort the given data in ascending order
The median is then calculated using:
This gives:
The median is the fifth item for both groups.
So, we have:
4.7 is greater than 4.3
Hence, (b) is true
Since (b) is true and only one option is correct, then (c) and (d) are incorrect
