A teacher divides her class into four groups. She assigns
babunello [35]

Group C : 32.1°C , 31.9°C, 31.8°C makes the most precise measurements of the object's temperature.

Precision :The degree of similarity between study results of the experiment if they were performed today under comparable conditions.

If repeated measurements yield similar results, the measurement is considered precise (or repeated surveys).

It means how closely all the results are related .

Therefore, there should be less difference between the measurements of all the results.

In option (a) , there is a difference of 1° in all the results.

In option (b) , there is a difference of approximately 1.5° in all the results.

In option (c), there is only 0.2° difference in all the results.

In option (d) , there is a difference of 3° in all the results.

Therefore, All the option of group (c) are closely related.

Hence, Group (c) 32.1°C, 31.9°C, 31.8°C makes the most precise

measurements of the object's temperature.

ivolga24 [154]

The term sensitivity in Analytical Chemistry is "the slope of the calibration curve or a function of analyte concentration or amount".

<u>Answer:</u> Option B

<u>Explanation:</u>

In a sample, the little amounts of substances can be accurately evaluated by a method is termed as "Analytical sensitivity". This detect a target analyte like an antibody or antigen, process is considered as potential of a test to and generally demonstrated as the analyte's minimum detectable concentration.

The acceptable diagnostic sensitivity is not guaranteed by high analytical sensitivity. The percentage of individuals who have a given disarray who are identified by the method as positive for the disarray is known as "Diagnostic sensitivity".
