Answer:
Juan did.
Step-by-step explanation:
the two fastest speeds are 26.47 and 26.9 seconds. In order to be able to properly work with that, you need to add a 0 to 26.9 so that it turns into 26.47 and 26.90 seconds. If you were yo subtract those, you would have:
26.90-26.47= 0.43
Therefore, 26.47 seconds is faster than 26.9 seconds.

Answer:
The F-Ratio increases as, the variability between means increases relative to the variability within groups
Step-by-step explanation:
The F-Ratio is given as follows;

Where;
= The variance between groups
= The variance within groups
Therefore, as the F-Ratio increases, the variability between groups (means) increases relation to the variability within groups
The answer is B because r is negative and less than the critical value.
