I've got these SPSS results refering to a study where horses and camels were injected with tripelenamine.


I have 2 questions:


1) How do I calculate the 95% confidence/trust interval for comparing the variability of the percentage of drugs in horses and camels' blood?


2) For a level of significance of 5%, is there sufficient statistical evidence to say
that, on average, the percentage of drugs in blood is equal in horses and camels after administration of tripelenamine?


I have no idea how to solve the first question. As for number 2, is the answer on the yellow box? Sorry for the dumb questions
