95% CI 1.03-1.7, p=.03
I want to understand the meaning of each of these terms.

All i know it that it means a score will fall between those two points 95% of the time.
I havn't started studying for stats yet.

It means you are 95% confident that the population mean or average will lie somewhere in between those two numbers. It makes the person conducting the study more confident because they a higher chance of having the actual average fall somewhere in between those two numbers, instead of just having one specific guess. I am taking statistics now, so I'm not the best at explaining things.

Your confidence is 95% that, if another reasonably large sample is taken of your population, the mean of the sample will lie within the interval
1.03 to 1.7, or 1.365 ± 0.335
1.365 is the mean of the data upon which you base your forecast. I believe p = 0.3 in this case is σ/√n = 0.3, where σ is the standard deviation of this sample, and n is the number sampled.
