Question

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 10 trials of this experiment.

590, 415, 393, 590, 472, 660, 649, 312, 521, 590

(a) what is the mean of this data set? if your answer is not an integer, round your answer to one decimal place.
(b) what is the median of this data set? if your answer is not an integer, round your answer to one decimal place.
(c) how many modes does the data set have, and what are their values? indicate the number of modes by clicking in the appropriate circle, and then indicate the value(s) of the mode(s), if applicable.
