William has a time of 17 minutes 30 seconds, and his team has a mean time of 20 minutes 15 seconds and a standard deviation of 1 minutes 15 seconds. Kelly has a time of 16 minutes 45 seconds, and her team has a mean of 18 minutes 45 seconds and a standard deviation of 15 seconds. Who has the faster time when compared to each of their teams?

It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.

We have:

Two runners, William and Kelly, want to find out who has the faster time when compared to each of their teams.

William has a time of 17 minutes 30 seconds

Mean(team) = 20 minutes 15 seconds

standard deviation = 1 minutes 15 seconds

Kelly has a time of 16 minutes 45 seconds,

Mean(team) = 18 minutes 45 seconds

standard deviation = 15 seconds

Based on the data we can say, Kelly has a faster time.

Thus, Kelly has a faster time because the standard deviation of William's team is 1 minute 15 seconds and for kelly is 15 seconds which is lower.
