Probability and Statistics

  • Probability
  • • concept of a normal distribution as an example of a continuous probability model and its mean and variance; use of N(μ, σ2) as a probability model
  • • standard normal distribution
  • • finding the value of P(X < x1) or a related probability, given the values of x1, μ, σ
  • • symmetry of the normal curve and its properties
  • • finding a relationship between x1, μ, σ given the value of P(X < x1), or a related probability
  • • solving problems involving the use of E(aX + b) and Var (aX + b)
  • • solving problems involving the use of E(aX + bY) and Var (aX + bY), where X and Y are independent
  • Discrete random variables
  • Normal Distribution
  • Sampling
  • Hypothesis testing
  • Correlation and Linear Regression

What is the difference between variance and standard deviation?

What is the difference between mutually exclusive and independent events?

How do I get better at statistics? All the different values such as pop mean or SD is so confusing. Any input will be greatly appreciated.

Anyone got any tips on statistics? I could really use the help...
