b. precise
c. both a and b
d. neither a nor b

question 18 *

1. the weather app predicts 75°f, 76°f, 74°f, and the actual temperature is 60°f. this application is:

a. accurate but not precise
b. precise but not accurate
c. both
d. neither

Explanation:

1. Question 17: Accuracy refers to how close a measurement is to the true or correct value. Precision refers to how close repeated measurements are to each other. Data close to the correct value is accurate.
2. Question 18: The predicted temperatures ($75^{\circ}F, 76^{\circ}F, 74^{\circ}F$) are close to each other (precise), but far from the actual temperature of $60^{\circ}F$, so not accurate.

Answer:

1. A. accurate
2. B. Precise but not accurate
