# Evaluating Mineral Content in Spinach## Study OverviewSix 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 IntervalTo 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 IntervalBased 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.
