Pitch perception enables us to arrange sounds on a melodic scale.There is fractional help for every one of Place theory, frequency theory, duplicity theory, and volley theory, showing that each of the three components assume a job in pitch observation.

A) Two dependent samples
Explanation:
According to a different source, these are the options that come with this question:
A) Two dependent samples
B) Two independent samples
Inference for these data will be based on the use of two dependent samples. Dependent samples are those in which each score in one sample is paired with a score in the other sample.
