Question

at a track meet the officials use a timer to determine the amount of time it takes to complete each running event. if the timer does not function correctly and adds one second onto each runners time this is an example of a random error. true false question 5 (2 points) when you measure the amount of sand for an experiment and add two grams of sand instead of one gram of sand, this is a random error. true false

Explanation:

1. In the first case, the timer adding a fixed one - second error to each runner's time is a systematic error as it is a consistent, non - random deviation. It affects all measurements in the same way.
2. In the second case, adding two grams of sand instead of one gram is likely a human or measurement error, but it is not a random error in the statistical sense. Random errors are fluctuations that occur unpredictably around the true value. These examples are more like systematic or blunder errors.

Answer:

1. False
2. False
