In an effort to estimate the mean length of stay for motel guests at a major national motel chain, the decision makers asked for a 95 percent confidence, and a margin of error of 0.25 days.
 
  Further, it was known that the population standard deviation is 0.50 days. Given this, the required sample size to estimate the mean length of stay is about 16 customers. Indicate whether the statement is true or false

Answer to Question 1

TRUE

Answer to Question 2

While there are several possible approaches to developing and conducting a written survey, there are several steps that most approaches would include. These are:

Define the issue  You need a clear understanding of what it is that you wish to learn from the survey.

Define the population of interest  You must determine who the people are that are to be surveyed. You need to be specific about this since those surveyed will hopefully represent the views of the entire population.

Design the survey instrument  You need to develop the questions that will get at the answers to your research questions. A written survey must be a reasonable length and the questions need to be well-written and clear. You need to be careful not to interject bias in the way the question is written. The survey design should be clear and easy for the respondents to use.

Pre-test  You should always pre-test the survey with a small subgroup from the population. Use their feedback to make constructive improvements in the survey and to make sure that you have included the right questions given your original objective.

Determine the sample size and sampling method  Whenever possible you want to survey a large number of people, but your sampling budget will limit you. It will be necessary to determine how many are needed for statistical validity and for meeting objectives. You also need to specify how the sample is to be selected from the populationstatistic al or nonstatisticaland specifically what sampling method to use.

Select the sample and administer the survey  The survey can be administered in several waysthrough the mail, on the Internet, or in person.
