mean= 1/2

Step-by-step explanation:

since, mean = sum of all observations/ no. of observations. sum of observations= (3/7 + 4/7) +(5/9+4/9) = (7/7)+ (9/9). = 1+1 =2. no. of observations= 4 , mean = 2/4= 1/2 if it would help you then follow me!!!!!!!

Answer 2

Answer:

1/2

Step-by-step explanation:

Mean: Sum of observations/No.of Observations

Observations : 3/7, 5/9, 4/7, 4/9

= ( 3/7 + 4/7 ) + ( 5/9 + 4/9 )

= 7/7 + 9/9

= 1 + 1

= 2

No. of Observations = 4

= 2/4

= 1/2
