What does the symmetric bell shape of the normal curve imply about the distribution of individuals in a normal population? [2 sentences]
Homework Answers
The symmetric shape of normal distribution implies that there are equal number of individuals above and below the mean of the distribution. It also implies that the distribution is not skewed towards any direction and hence the mean, median and mode of the distribution is the same.

Describe the standard normal distribution. What are its characteristics? Choose the correct answer below. O A. The standard normal distribution is a normal probability distribution with mean u = 0 and standard deviation o = 1. Similar to any normal probability distribution, it has associated with it a bell-shaped curve, symmetric about a vertical line through u with inflection points at o and -o. The Z-scores theorem, along with a table of areas under this standard normal curve can be...

. In probability theory, the Normal Distribution (sometimes called a Gaussian Distribution or Bell Curve) is a very common continuous probability distribution. Normal distributions are important in statistics and are often used in the natural and social sciences to represent real-valued random variables whose distributions are not known.

Discuss a sampling distribution by describing 1. A population, 2. A variable on the individuals in that population, 3. a standard deviation for that variable, and 4. the size of a sample from that population. Compare the 5. center, 6. variability, and 7. shape of the sampling distribution of the mean of that sample with those of the population distribution. What does the sampling distribution tell us about the population?
