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
