HW Assignment 2 Part 1 Solicit four non-student residents of the Grand Rapids metro area (coworkers, family members, church members, people at the club, etc.) to complete the Bike Friendly GR survey online by Sunday, April 10, 2011. You will receive 5 points for each respondent for a total of no more than 20 points on one of the remaining homework assignments. Ensure that your respondents know your full name. They will be required to input that information at the end of the survey. Participants will be validated. Part 2 Calculate the optimum sample size for Bike Friendly GR given the following. (Show your work for partial credit.) Imagine that the survey consists primarily of probability questions. Secondary data indicates that 70% of the GR population is interested in bike riding to some degree.

They estimate that the population of bike riders in GR is approximately 1,100 people. What is the optimal sample size?
