Answer:

See below ~

Step-by-step explanation:

Q1

  • Number of students surveyed = 80 + 60 + 30 + 40
  • Number of students surveyed = 140 + 70
  • Number of students surveyed = 210

Q2

  • Relative Frequency (aquarium) = 80/210 = 8/21
  • Relative Frequency (aquarium) = 0.38

Q3

  • P (aquarium) = 80/210 = 8/21
  • P (aquarium) = 38.1%

Q4

  • Let x be the number of students in the whole school who would choose the aquarium. Then, the proportion would be :
  • x/1000 = 8/21
  • x = 8000/21
  • x = 381 students (nearest whole number)
