a)  The graph shows   the number of adults and youths that go to the movies on Friday, Saturday and Sunday

 

b)  The inference that  can be  made is that Friday  is a more  popular day  for  adults  while Saturday and Sunday are more popular days for youths

 

c)   

i)   Is true....Saturday is the  most popular day 

Attendance on Friday  = 650 + 300  = 950

Attendance on Saturday  =    (>500)  + 650   = > 1150

 Attendance on Sunday  =  (>300) + 500  = > 800

 

ii)   Adult attendance   650 + (>500) + (>300)  = >  1450

      Youth Attendance =  300 + 650  + 500 =  1450

Note that  (ii)  is also true.....the adult and youth attendance  are approximately equal
