Question

A music therapist was interested in investigating whether listening to music or composing music had an influence on both anxiety levels and oxygen saturation in children who were hospitalized for asthma-related illnesses. Thirty-two children spent 20 minutes listening to classical waltzes played on a piano. On a different day, they spent 20 minutes composing their own short pieces of music using a software program.
When listening to music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was smaller than the test statistic for the observed data.
When composing music: For the physiological measure, the critical value for t was larger than the test statistic for the observed data. For the anxiety measure, the critical value for t was larger than the test statistic for the observed data.
When writing the results of the music therapist's study, which of these statements reflects the correct conclusions that should be drawn from the results and then included as part of the interpretation paragraph?Question 8 options:
a) Music therapists should make pediatric asthma patients compose music in order to increase their oxygen saturation.
b) Music therapists should make pediatric asthma patients listen to music in order to reduce their anxiety.
c) Pediatric asthma patients should listen to music in order to increase their oxygen saturation.
d) Additional information is needed to draw a proper conclusion.

Answer 1

Answer:

The correct conclusion is;

d) Additional information is needed to draw a proper conclussion

Step-by-step explanation:

The given parameters are;

When listening to music;

Physiological measure Critical t > Test statistic Accept H₀

Anxiety measure Critical t < Test statistic Reject H₀

When composing music;

Physiological measure Critical t > Test statistic Accept H₀

Anxiety measure Critical t > Test statistic Accept H₀

When the test statistic is larger the critical 't'

Therefore, the test suggest that there is no difference between physiological and anxiety influence of composing music on pediatric asthma patients

There is sufficient statistical evidence to suggest that listening to music has an influence on the anxiety of pediatric asthma patients however, the nature of the influence is not specified and more information is needed to draw a proper conclusion
