Question:
Student researchers Adam, Edward, and Kian wondered if music would affect performance for certain tasks. To find out, they had student volunteers sort a shuffled set of 26 playing cards by face value and by color. Nineteen of the 38 volunteers were randomly assigned to listen to music during the sorting, while the others listened to no music. Here are parallel boxplots of the time in seconds that it took to sort the cards for the students in each group:
Do these data give convincing evidence of a difference in the true mean sorting times at the 
significance level?
a. State appropriate hypotheses for performing a significance test. Be sure to define the parameters of interest.
b. Check if the conditions for performing the test are met.
