Central limit theory

• Define the central limit theory

  If you take samples from a distribution and calultate the sample means.

  Plot the sample means and the distribution approximates a normal distribution.
• What is the graph produced by the central limit theory

  The sampling distribution of the sampling mean
• What are the types of uniform distribution

  Discrete and continuous
• What happens to the sampling distribution of the sampling means as sample size increased

  It gets closer to a normal distribution
• What is the recommemded sample size for the central limit theory

  Over 30
• What is the significance level

  
  

  This is the probability that the null hypothesis is true
• What is the symbol for the significance level

  Alpha
• What is the null hypothesis symbol

  H 0
• What is the null hypothesis

  That there is no significant difference
• What is H1

  The alternative hypothesis
• What is the P-value

  The probability of observing the outcome or any outcome which is more extreme
