# Evaluating Mineral Content in Spinach ## Study Overview Six measurements were made of the mineral content (in percent) of spinach. It is reasonable to assume that the population is approximately normal. The measurements are as follows: - 19.1% - 20.9% - 20.8% - 21.2% - 20.2% - 19.3% This data can be sent directly to Excel for analysis. ## Statistical Analysis ### Part 1 of 2 #### Construct a 99% Confidence Interval To determine the mean mineral content of spinach, construct a 99% confidence interval. Round all answers to two decimal places. \[ \text{A 99% confidence interval for the mean mineral content is} \quad < \mu < \] **Input fields:** Two boxes are provided to enter the lower and upper bounds of the confidence interval. ### Part 2 of 2 #### Interpretation of Confidence Interval Based on the confidence interval, is it reasonable to believe that the mean mineral content of spinach may be greater than 25%? Provide an explanation. **Input field:** A dropdown menu allows the selection of an answer, followed by a text box to provide an explanation. Options include: - It is reasonable - It is not reasonable **Control Buttons:** - **Continue** button to proceed - **Submit Assignment** button to complete the task --- This task requires understanding of confidence intervals and statistical inference to assess nutrient content reliability.
