Olivia Trent is a newly hired systems analyst with your group. Olivia has always felt that questionnaires are a waste. Now that you will be doing a systems project for Ground Ride Sharing (GRS), a national ride sharing firm with branches and employees in 130 cities, you want to use a questionnaire to elicit some opinions about the current and proposed systems.
a. Based on what you know about Olivia and G R S, list three persuasive reasons Olivia should use a survey for this study. b. Given your careful arguments, Olivia has agreed to use a questionnaire but strongly urges that all questions be open-ended so as not to constrain the respondents. In a paragraph, persuade Olivia that closed questions are useful as well. Be sure to point out trade-offs involved with each question type.
Use a multiple-line IF statement to assign the value zero to the variable count when the value of count exceeds 99.
What will be an ideal response?
