PLEASE PROVIDE ACCURATE ANSWERS

High school students were randomly sorted into one of two groups. Members of each group performed a series of mental tasks while music was playing in the background. One group listened to classical music and the other to rock music. It is
hypothesized that less tasks will be completed with classical than with rock music. What can be concluded with a = 0.10? The results are below:
classical
rock
û, = 30.69
ô1 = 4.59
i, = 33.34
02 = 5.32
n2 = 13
ni = 14
