Question 88

An automation engineer investigated the efficiency of two software control algorithms, Algorithm Alpha and Algorithm Beta, used by a robotic arm to perform a precision micro-soldering task.

The results of the testing trials are summarized in Table 1 below.

Table 1: Completion times (in seconds) for a micro-soldering task under two software control algorithms

Algorithm AlphaAlgorithm Beta
Mean completion time (seconds)14.219.8
Standard deviation (seconds)0.452.15

What conclusions might be drawn from the data in Table 1? Refer to both the means and standard deviations in your answer.
