**Educational Website Content: Understanding Normal Distribution through Chocolate Chip Cookies**

The number of chocolate chips in an 18-ounce bag of chocolate chip cookies is approximately normally distributed with a mean of 1252 chips and a standard deviation of 129 chips. Let's explore some important statistical concepts using this data:

### Exercises

1. **Probability Between Two Values:**
- **Question (a):** What is the probability that a randomly selected bag contains between 1000 and 1400 chocolate chips, inclusive?

2. **Probability of Fewer Than a Specific Value:**
- **Question (b):** What is the probability that a randomly selected bag contains fewer than 1050 chocolate chips?

3. **Proportion of Bags with More Than a Specific Value:**
- **Question (c):** What proportion of bags contains more than 1175 chocolate chips?

4. **Percentile Rank Calculation:**
- **Question (d):** What is the percentile rank of a bag that contains 1450 chocolate chips?

### Visualizing the Normal Distribution

To solve these problems, it's essential to visualize the distribution:

- **Normal Distribution Concept:** Suppose a random variable \( X \) is normally distributed with mean \( \mu \) and standard deviation \( \sigma \). The area below the normal curve represents a proportion or probability.

- **Calculating Probabilities Using Curves:**
- **Exercise (a) Visualization:**
- To calculate the probability \( P(1000 \leq X \leq 1400) \), identify the correct shaded area on a normal curve.
- **Correct Curve (Option B):** This curve illustrates the area between 1000 and 1400 highlighted to show the probability of a bag falling within this range.

- **Technology Usage:**
- Use statistical software or tools to find the shaded area representing the probability or proportion.
- **Note:** Round the shaded area to four decimal places for precision.

Understanding these components demonstrates how to work with normally distributed data in a practical context, aiding in calculating probabilities and analyzing distributions effectively.

Definition Definition Measure of central tendency that is the average of a given data set. The mean value is evaluated as the quotient of the sum of all observations by the sample size. The mean, in contrast to a median, is affected by extreme values. Very large or very small values can distract the mean from the center of the data. Arithmetic mean: The most common type of mean is the arithmetic mean. It is evaluated using the formula: μ = 1 N ∑ i = 1 N x i Other types of means are the geometric mean, logarithmic mean, and harmonic mean. Geometric mean: The nth root of the product of n observations from a data set is defined as the geometric mean of the set: G = x 1 x 2 ... x n n Logarithmic mean: The difference of the natural logarithms of the two numbers, divided by the difference between the numbers is the logarithmic mean of the two numbers. The logarithmic mean is used particularly in heat transfer and mass transfer. ln x 2 − ln x 1 x 2 − x 1 Harmonic mean: The inverse of the arithmetic mean of the inverses of all the numbers in a data set is the harmonic mean of the data. 1 1 x 1 + 1 x 2 + ...
