Question

Refer to the accompanying table, which describes the number of adults in groups of five who reported sleepwalking. Find the mean and standard deviation for the numbers of sleepwalkers in groups of five.

**Probability Distribution Table**

The following table represents a discrete probability distribution.

| x | P(x) |
|---|------|
| 0 | 0.175 |
| 1 | 0.357 |
| 2 | 0.318 |
| 3 | 0.118 |
| 4 | 0.028 |
| 5 | 0.004 |

**Explanation:**
- **x**: Represents the random variable, which can take integer values from 0 to 5.
- **P(x)**: Represents the probability of the random variable x occurring.

This table can be used to study the probabilities associated with different outcomes of a random event. You can see that for x = 1, the probability P(x) is the highest at 0.357, while for x = 5, the probability P(x) is the lowest at 0.004.

In practice, such distributions can be used in various fields such as economics, engineering, and social sciences to predict outcomes and make informed decisions based on the likelihood of different possibilities.

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 + ...
