Answer: More grandparents prefer using hard copy rather than a digital copy.
Step-by-step explanation:
Given: The total number of grandparents surveyed = 250
which is 10 times n where n is the sample size = 25
i.e. we need to multiply 10 to each number given in picture.
Therefore, the number of grandparents surveyed prefer digital copy =[tex]4\times10=40[/tex]
The number of grandparents surveyed prefer digital copy =[tex]21\times10=210[/tex]
Clearly 210>40
Therefore, More grandparents prefer using hard copy rather than a digital copy.
