A population has a standard deviation of 5.5. What is the standard error of the sampling distribution if the sample size is 81?

VladimirAG [237]

Answer:

$\sigma = 5.5$

And we have a sample size of n =81. We want to estimate the standard error of the sampling distribution $\bar X$ and for this case we know that the distribution is given by:

$\bar X \sim N(\mu ,\frac{\sigma}{\sqrt{n}})$

And the standard error would be:

$\sigma_{\bar x}= \frac{\sigma}{\sqrt{n}}$

And replacing we got:

$\sigma_{\bar x}=\frac{5.5}{\sqrt{81}}= 0.611$

Step-by-step explanation:

Solve the following equation for x, in terms of a and b. ax = 15 + bx

charle [14.2K]

Value of x will be $x=\frac{15}{a-b}$ .

Equation given in the question → $ax=15+bx$

To find the value of 'x' in terms of a and b, we will simplify the given equation,

$ax=15+bx$

$ax-bx=(15+bx)-bx$

$x(a-b)=15$

$x=\frac{15}{a-b}$

Therefore, Values to filled → Blank 1 = 15

Blank 2 = (a - b)

Write a polynomial to represent the value of d dimes and n nickels.

nadya68 [22]

Answer: 0.10d + 0.05n
Note: this value expression is in dollars (not cents)
If you want the expression in cents instead of dollars, then it would be 10d+5n

--------------------------------------------------------------------------------

The value of just the dimes only is 0.10d dollars
The value of just the nickels only is 0.05n dollars
Combined the total value is 0.10d+0.05n dollars
