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. 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. none of the other answers are correct
