Question

The graph illustrates a normal distribution for the prices paid for a particular model of HD television. The mean price paid is $1600 and the standard deviation is $140.

What is the approximate percentage of buyers who paid less than $1320?

What is the approximate percentage of buyers who paid less than $1180?

 

 

The image displays a portion of an educational platform focused on teaching statistics, specifically regarding normal distribution and the 68-95-99.7 rule.

### Graph Explanation
The graph is a bell-shaped curve representing a normal distribution of prices. The x-axis is labeled "Distribution of Prices" with tick marks at intervals from 1180 to 2020. The peak of the graph is around the midpoint, suggesting the mean price.

### Questions and Content
1. **Platform**: STAC Moodlerooms for a course titled MATH 120 - Section B, Fall 2020.
2. **Course Navigation**: Links to sections like 'Week 1: Variables and Data Wrangling', 'Week 2: Measures of Center, Scatterplots, the Grammar of Graphics', and others.
3. **Current Content**: 
   - Questions related to the graph. 
   - Example: "What is the approximate percentage of buyers who paid between $1600 and $1740?" with a correct result of 34%.

### Educational Context
The lesson is part of a series on statistical distributions, aiming to help students understand key concepts of normal distribution and apply the 68-95-99.7 rule.

### Navigation
- Progress through lectures, with the next topics being 'Z-scores'.

This setup helps students grasp statistical concepts through interactive questions, graphs, and structured course materials.
