Fast jason and matt have developed a new computerized timer for recording race times. which of the following would be the best way to confirm the timer's accuracy? (2 points) a. independent testing, repeated in multiple trials b. consistent testing conducted by a single person c. first-person testimony from a variety of racers d. multiple publications of data in a wide range of media

Option A, Independent testing,repeated in multiple trials

Explanation:

For testing the accuracy of any device, it would be essential to test it randomly on independent observant so that the variability in data set could be captured. Based on this data analysis, corrections in the measuring device must be made. After the corrections, the device must be tested again on the random samples to calculate its accuracy. Independent testing gives unbiased results, while restricted sample testing give biased result.

Hence, option A is correct.

answer; /// i believe the correct answer is (reactants);

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d
