5 steps
● State the hypothesis
● Find threshold ( p value of > 0.05)
● Collect the data and calculate the statistics
● Determine the critical values
● Make a decision (reject or fail to reject)
a) There is no significant difference in a students mood when beginning class with a song
of their choosing compared to when they don't play any music
b) In the beginning of class if a student chooses a song they like, it will significantly improve
their mood than when not playing a song in the beginning of class.
c) In the beginning of class playing a song of their liking will neither improve or worsen the
mood of the student
d) If we fail to reject the hypothesis we still don't have enough evidence support so it
doesn't necessarily mean we are right, it just means we cant discard this option, we fail
to reject based on insufficient evidence.
e) If we reject null hypothesis it means that it is statistically significant playing a song at the
beginning of class, supporting the hypothesis
