Q. Without looking, Eddie flipped to a page in the phone book and called a number from that page. Repeating that approach, he called 643643 phone numbers from the phone book.\newlineIs this sample of the phone numbers in the phone book likely to be representative?\newlineChoices:\newline(A) yes\newline(B) no
  1. Method of Selection: Understand the method Eddie used to select phone numbers.\newlineEddie flipped to a page randomly and chose a number without looking. This method is random.
  2. Sample Size Consideration: Consider the size of the sample relative to the method of selection.\newlineEddie called 643643 phone numbers. Assuming the phone book contains thousands of numbers, 643643 is a significant sample size.
  3. Randomness Analysis: Analyze the randomness of the selection process.\newlineSince Eddie's selection was random each time, each number had an equal chance of being selected. This randomness helps in making the sample representative.
