The following data represent the pH of rain for a random sample of 12 rain dates. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers. C) Construct and interpret a 99% confidence interval for the mean pH of rainwater. (Use the ascending order. Round to two decimal places as needed.) There is 99% confidence that the population mean pH of rain water is between ___ and ___.

The image shows a table with numerical data and a snippet of an online educational platform interface.

**Table Data:**
- **Column 1:** 5.58, 5.02, 4.87
- **Column 2:** 5.72, 4.58, 4.76
- **Column 3:** 4.99, 4.74, 4.56
- **Column 4:** 4.80, 5.19, 5.69

**Interface Elements:**
- There is a message prompting users to complete their choice by filling in answer boxes.
- A clear visual button is present for users to "Check answer."
- An option to "Clear all" inputs is available.

**Additional Information:**
- The bottom portion of the interface shows the current temperature and weather condition, indicating "68°F" and "Mostly cloudy."
- The time and date displayed on the interface are "4:38 PM" and "1/15/2022."

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
