Jose times how long sugar takes to dissolve in warm water. He conducts four trials of his experiment. What should he conclude from his data?

Time:

trial
1
30 seconds


trial
2
32 seconds

trial
3
10 seconds

trial
4
29 seconds

Sugar does not dissolve in water.

The time recorded for Trial 3 may be inaccurate.

His experiment has very low precision.

it's either B or C, I can't find the answer.

Based on the data provided, the most appropriate conclusion for Jose to draw from his data is:

His experiment has very low precision.

The reason for this conclusion is that the recorded times for the four trials are quite different from one another, ranging from 10 seconds to 32 seconds. This suggests that the results are not consistent or reliable, indicating low precision in the experimental process.

To analyze the data and determine the conclusion, let's look at the information provided:

Trial 1: 30 seconds
Trial 2: 32 seconds
Trial 3: 10 seconds
Trial 4: 29 seconds

From the data, it seems that the sugar does dissolve in warm water because there are observable changes in the dissolution time across the trials. Trials 1, 2, and 4 recorded reasonably similar times, indicating consistency in the rate of sugar dissolution. However, Trial 3 stands out with a significantly shorter time of 10 seconds.

Given this, we can conclude that the time recorded for Trial 3 is likely inaccurate. It is improbable for sugar to dissolve in warm water in only 10 seconds, especially when the other trials took longer. Therefore, we can eliminate the possibility that sugar does not dissolve in water based on this data.

Regarding the precision of the experiment, considering the range of times recorded (10 seconds to 32 seconds), it can be determined that there is some variability in the measurements. While Trials 1, 2, and 4 are relatively close, Trial 3 deviates from the pattern. This inconsistency suggests that the experiment may have low precision.

Therefore, the correct conclusion from the data is that the time recorded for Trial 3 may be inaccurate, and the experiment demonstrates relatively low precision. Hence, the answer is both B and C.

IF it was the same amount of sugar, the trial 3 is most suspect.
