(a) Which measures of central tendency do not exist for this data set? Choose all that apply.MeanMedianModeAll of these measures exist(b) Suppose that the measurement 191 (the smallest measurement in the data set) were replaced by 69. Which measures of central tendency would be affected by the change? Choose all that apply.MeanMedianModeNone of these measures(c) Suppose that, starting with the original data set, the largest measurement were removed. Which measures of central tendency would be changed from those of the original data set? Choose all that apply.MeanMedianModeNone of these measures

On each trial of an experiment, a participant is presented with a constant soft noise, which is interrupted at some unpredictable time by a slightly louder sound. The time it takes for the participant to react to the louder sound is recorded. The following list contains the reaction times (in milliseconds) for 25 trials of this experiment. 191, 213, 218, 222, 226, 235, 252, 268, 268, 284, 291, 310, 310, 323, 326, 344, 361, 365, 389, 428, 445, 460, 531, 747, 883 Send data to calculator Frequency 12+ 11 10 10 8 - 6- 4 2 N 150 300 450 600 750 1000 Reaction time (in milliseconds) Answer the questions below
