Answer:B. 42, 43
Explanation:
STEP 1 Listing out the data set
Country Time with dad
Belgium 30
 Canada 44
 China 54 
Finland 50
 Germany 36 
Nigeria 42 
Sweden 46 
United States 42
STEP 2--- finding the mode and median
Mode----The mode of this data set is the number that occurs most frequently in this research date. 
Time with dad in ascending order is given as 30, 36, 42, 42, 44,46,50,54
The number that occurred the most is 42 = mode
Median The median is the middle value in a data set 
Since these data set is an even number, we take the average of the two middle numbers 
 Arranging in ascending order, we have 
30, 36, 42, 42, 44, 46, 50, 54---------------42 and 44 are the middle numbers 
 42+ 44/2 =43
Therefore mode and median are 42 and 43 respectively
