Answer

Answer:

  1. sending a mandatory and confidential e - mail survey to every tenth employee of a company to determine overall job satisfaction
  2. taking a poll in the main hallway between classes to determine the number of students who would be interested in a school trip to New York City

Explanation:

Step1: Analyze first option

A year - book only represents students in a particular school or group of schools, not all girls in the US. So it's not a fair sample.

Step2: Analyze second option

People exiting a vitamin store are likely more health - conscious and exercise more than the average American. So it's a biased sample.

Step3: Analyze third option

Calling only registered members of the national Republican Party to determine city mayoral race voter turnout is biased as it only represents one political party and not the entire voting population of the city.

Step4: Analyze fourth option

Sending a survey to every tenth employee of a company is a form of systematic sampling. If the company is large enough, it can give a fairly representative view of overall job satisfaction among employees.

Step5: Analyze fifth option

Taking a poll in the main hallway between classes gives a chance for a wide range of students to be surveyed about their interest in a school trip. It can be a fairly representative sample of students interested in the trip.
