Exercises L3: Probability Theory
... 6. A car driver has caused an accident and has to take an alcohol test. Research has shown that 75% of the persons who had (too much) alcohol shows a positive test result. However, 2% of the persons who did not drink also show a positive test result. Assume that in case of accidents 5% of the car dr ...

Week 1: Descriptive Statistics
... A construction company has the opportunity to bid on three jobs (A,B and C). From historical data the company believes its changes of winning each job is 0.20, 0.50 and 0.10. Its chances of winning all three jobs is 0.05. The probability that it will win both A and B is 0.10. For A and C and B and C ...

Hypothesis Testing for Large Sample
... The Significance Level is denoted by α Commonly, a significance level of 0.05 or 0.01 is considered If for example, an α of 0.05 is chosen in designing a decision, then there are about 5 chances in 100 that we would reject the hypothesis when it should be accepted, that is we are 95% confident that ...

Solutions
... The p-value is about 4.4%, which means that you would reject the Null Hypothesis at the 10% (this is a two-tailed test) significance level, but not at any level below 8.8%. Testing for equality of two means (clearly, this refers to both data sets) ...

... Ruth hit 60 home runs in 1927. Roger Maris hit 61 in 1961, Mark McGwire hit 70 in 1998 and Barry Bonds hit 73 in 2001. In an absolute sense, Barry Bonds had the best performance of these four players, since he hit the most home runs in a single season. However, in a relative sense this may not be tr ...

Intro to Probability
... In genes, there are dominant (G) and recessive (g) traits. Each person carries 2 traits. If at least one trait is dominant (GG or Gg), then the person portrays that trait. Only if both are recessive (gg) does the person portray the recessive trait. When a parent has both a dominant and a recessive g ...
