The price of gold is often reported per ounce. At the end of 2005, this price was $513. At the end of 2015, it was $1060. By wha

erastova [34]

Answer:

106.63%.

Step-by-step explanation:

We have been given that at the end of 2005, this price was $513. At the end of 2015, it was $1060.

To find the percentage of the price per ounce of gold increase we will use % increase formula.

$\text{Percent Increase}=\frac{\text{Final value-Initial value}}{\text{Initial value}}\times 100$

Let us substitute our given values in above formula.

$\text{Percent Increase}=\frac{1060-513}{513}\times 100$

$\text{Percent Increase}=\frac{547}{513}\times 100$

$\text{Percent Increase}=1.0662768031189084\times 100$

$\text{Percent Increase}=106.62768031189084\approx 106.63$

Therefore, the price of per ounce of gold increased by 106.63%.

Calculating the degrees of freedom, the sample variance, and the estimated standard error for evaluations.

ki77a [65]

Answer:

The variance is $\sigma ^2 =25$

Step-by-step explanation:

From the question we are told that

The sample size is n = 21

The sum of squares is $SS = 500$

Generally the variance is mathematically represented as

$\sigma ^2 = \frac{SS}{n- 1}$

substituting values

$\sigma ^2 = \frac{ 500}{21- 1}$

$\sigma ^2 =25$
