6. 8. A soft drink factory produces 1700 bottles a day. The factory tested a sample of 250 units and found that 7 were defective. By calculating the experimental probability that a bottle is defective, determine how many defective bottles would be expected in a week (the factory runs 7 days a week).

• 333 bottles/week

• 49 bottles

• 7 bottles

• 242 bottles
