Need help filling out GC data analysis table, analysis of GC data, and post-lab questions.

In order to answer them, I first need help with filling out the GC data analysis table and its analysis section. This consists of labeling on the spectrum and doing calculations. I provided all the necessary information.
Just to note for the question, “1. Print the spectrum for your assigned base only”. The base I used is isobutoxide which is labeled on the top. It is also labeled “308-001 bench 5.” This is the one that needs to be labeled and clearly show the compound structure that corresponds to each peak.
