本人理工科出身，想转行经济。没怎么系统的学过经济。现在遇到以下问题，望达人帮助解惑。先谢谢啦！

题目：

1. I own a long call option. Draw a graph of the option's value at maturity time on the Y-axis and the underlying (stock) price on the X-axis. The Strike price is somewhere on the middle of the x-axis, pick an aribitrary point.

Given some basic information on the stock price, draw a line of the options value one month away from amturity.

第一问是这样么：
至于第二问，我实在不知道。。。望解惑。谢谢。

2. 1 year interest rates are 5% and 2-year interest rates are 5.5%. What is the market saying about 1 year interest rates in a years time?
没概念啊。。。怎么做？谢谢！

另外，还有一道题要请教：
a drug trial gives the result that the drug works better than the placebo, with 95% confidence. What exactly does this statement mean? What further assumptions are needed to be able to deduce that the probability of the drug working is actually 95%?
谢谢。
