    Question

    Which of the following is a property of a normal

    distribution?
    A It is bimodal Correct Answer Incorrect Answer
    B It is skewed Correct Answer Incorrect Answer
    C It has a mean of zero and standard deviation of one Correct Answer Incorrect Answer
    D It is symmetric about the mean Correct Answer Incorrect Answer

    Solution

    The normal distribution, also known as the Gaussian distribution, has several key properties: 1. Symmetry: It is symmetric around its mean (ΞΌ), meaning the left and right sides of the distribution are mirror images. 2. Mean, Median, and Mode: These are all equal and located at the center of the distribution. 3. Bell-Shaped Curve: The graph of the normal distribution is bell-shaped and peaks at the mean. 4. Asymptotic: The tails approach the horizontal axis but never touch it. 5. Defined by Mean and Standard Deviation: Completely characterized by its mean (ΞΌ) and standard deviation (Οƒ). 6. Empirical Rule: Approximately 68% of data falls within Β±1Οƒ, 95% within Β±2Οƒ, and 99.7% within Β±3Οƒ of the mean
