Elyse, a marketing researcher, used SPSS to estimate the confidence interval for the mean response
to the following survey item:
When choosing a restaurant, how important is it to you that the restaurant offers gluten-free menu
options?
Responses were measured using the following scale:
1-not important at all
2- not very important
3-neutral
4-somewhat important
5-very important
Elyse determines the mean response is 4.2. The SPSS output indicates the confidence interval for
the mean is 4.0 to 4.4.
What does this indicate?
O We are 99% confident that the population mean is somewhere between 4.0 and 4.4, indicating that gluten-
free menu options are somewhat important to people who are part of the population.
O We are 95% confident that the population mean is somewhere between 4.0 and 4.4, indicating that gluten-
free menu options are somewhat important to people who are part of the population.
O We are 95% confident that the population mean is somewhere between 4.0 and 4.4, indicating that gluten-
free menu options are very important to people who are part of the population.
