Answer:
The confidence scale represents an ordinal scale of measurement
Explanation:
An ordinal scale or level of measurement is used to measure attributes that can be ranked or ordered, but the interval between the attributes do not have quantitative significance. In this case, the measurement was done on a scale of 1 - 7, with a "1" being; not all that race of defendant has an impact on jury verdicts and a "7" being "very" meaning that race indeed has impact on jury verdicts. Another example can be a survey carried out on the level of customer satisfaction on a particular product, with "1" most dissatisfied and "10 " representing most satisfied. In the first example, it is wrong to say that the difference between 1 being "not at all" and maybe 3 is the same as the difference between 5 and 7 which have different connotations, because the numbers are merely for tagging and not to quantify.
Other levels of measurement include:
1. Nominal: this is the simplest level of measurement and it is simply used to categorize the attributes. Example is taking a survey on gender in the categories of male, female and transgender.
2. Interval: the interval scale is used when the distance between two attributes have meanings but there is no true zero value associated with the scale.
3. Ratio: this combines all the other three levels of measurement and is used to categorize, used to show ranking, has meaningful distances between the attributes and the scale has a true zero point. Example is the measurement of temperature using the celcius scale thermometer, where there is a true zero point at 0°C and the distance between 5°C and 10°C is the same as the distance between 10°C and 15°C.

Explanation:
From the given information:
Strain fracture toughness 
= 75 MPa
Tensile stress 
= 361 MPa
Value of Y = 1.03
Thus, the minimum length of the critical interior surface crack which will result to fracture can be determined by using the formula:
![a_c = \dfrac{1}{\pi} ( \dfrac{k_k}{\sigma Y})^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ \dfrac{75 \times \sqrt{10^3}}{361 \times 1.03 } \Big]^2 \\ \\ a_c = \dfrac{1}{\pi} \Big [ 6.378474693\Big]^2 \\ \\ \mathbf{ a_c = 12.95 \ mm}](https://tex.z-dn.net/?f=a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%28%20%5Cdfrac%7Bk_k%7D%7B%5Csigma%20Y%7D%29%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%20%5Cdfrac%7B75%20%5Ctimes%20%5Csqrt%7B10%5E3%7D%7D%7B361%20%5Ctimes%201.03%20%7D%20%5CBig%5D%5E2%20%5C%5C%20%5C%5C%20%20a_c%20%3D%20%5Cdfrac%7B1%7D%7B%5Cpi%7D%20%5CBig%20%5B%206.378474693%5CBig%5D%5E2%20%20%5C%5C%20%5C%5C%20%5Cmathbf%7B%20a_c%20%3D%2012.95%20%5C%20mm%7D)
