Please help me find the mean and standard deviation

We found that the mean is μ = 3.5 and the standard deviation is σ = 1.7078.

Now, suppose that instead of tossing one die and counting the number of dots facing up we toss two dice and let $\overline{X}$ = the mean number of dots facing up on the two dice.

Note that when tossing 2 dice, $\overline{X}$ could end up being 1.0, 1.5, 2.0, 2.5, 3.0, 3.5, 4.0, 4.5, 5.0, 5.5, or 6.0.

$\overline{X}$ is a random variable. We call the expected value (also known as the mean) of this random variable E($\overline{X}$) or μ$_{\overline{X}}$. Your text uses the symbol μ$_{\overline{X}}$.

The standard deviation of $\overline{X}$, also called the standard error of the mean is denoted by the symbol σ$_{\overline{X}}$. It is easy to calculate once you know σ, which you found on MAC15. Review Chapter 7 if you’ve forgotten the formula. Then complete the following sentence:

When tossing two dice and finding the mean, $\overline{X}$, we find that $\overline{X}$ has a mean or expected value,

μ$_{\overline{X}}$ = ________ and a standard deviation σ$_{\overline{X}}$ = ________.

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 + ...
