those are five out of the 20 that I did and if those are right then the others are probably correct. My question is. What is the difference between a minor interval and a diminished interval? #5 to me looks like a m5 rather than a d5. Could somebody explain to me why it isn't an m5? Is it because You cannot have a Major 5th, because it's a Perfect 5th; therefore when you flatten the second note it's diminished and not minor? Thanks!
Making a Perfect interval smaller by a half step (raising the lower note or lowering the upper) makes it diminished. Making a Perfect interval larger by a half step makes it augmented. The reason for the glitch in the naming is historical. Its best just to memorize this stuff and get on with making music. Good Luck.

Doh! I can't believe I got #2 wrong that was an easy one, thanks for catching it though.
"Making a Perfect interval smaller by a half step (raising the lower note or lowering the upper) makes it diminished"
Yea but lowering a perfect or major interval by half step, isn't that also making a minor interval?
No, and that's just the definition. Lower a *major* interval by a half step, and you get a minor interval. Lower a *perfect* interval by a half step, and you get a diminished interval. Lower a *minor *interval by a half step, and you also get a diminished interval. That's just how it is.

okay okay so I lower a major and I get a minor and if I lower a perfect I get a diminished. Okay, my college book actually says "lower a major OR perfect by 1/2 step. The result is a minor" and then it says "lower a perfect by a half step and the result is a diminished"... I guess that's a typo?

yes, typo.
and, no, the naming convention between perfects vs. majors aren't arbitrary. the reason why perfects are perfects is because when you invert a perfect interval, you get a perfect interval (4th to 5th and vice versa). with majors/minors, you invert one, you get the other.
I've posted a short lesson for Intervals on the sputnikmusic.com bass lessons, music theory section. You'll have all the information you need in your textbook, but sometimes it's good to learn from various sources.
