Find the mean of the following set of data. 21.1.24 min 1.22 min 1.21 min 1.25 min Assume the data above is used to predict the average time it takes a swimmer to complete two laps in a pool. Use the Mean from the data set to compute the absolute error and Relative error if the actual time it takes the swimmer to Complete the two laps is 1.26 minutes. Round to two Decimal places if necessary.
A) Mean: 1.23 min; AE: 0.03 min; RE: ≈ 23.%8
B) Mean: 1.23 min; AE: 0.03 min; RE: ≈ 11.%9
C) Mean: 1.22 min; AE: 0.04 min; RE: ≈ 31.%7
D) Mean: 1.24 min; AE: 0.02 min; RE: ≈ 15.%9
E) None of these

Quizplus · Accepted Answer

Mean = (21.1 + 1.22 + 1.21 + 1.25) / 4 = 1.23 minAbsolute Error (AE) = |1.23 - 1.26| = 0.03 minRelative Error (RE) = (0.03 / 1.26) * 100 ≈ 23.8%
