Statistical Inference The Central Limits Theorem: When samples are large (above 30) the sampling distribution will take the shape of a normal distribution regardless of the shape of the population Ultimate Goal Accepting or Rejecting the NULL hypothesis Accept or Reject? We accept a null hypothesis when the significance level greater than .05 Reject when less than .05 Confidence Intervals First you have to know three things: Statistical inference: the process

useful for understanding statistical behaviors of random quantities. It plays a role in a number of widely-used statistical analyses‚ including the Student ’s t-test for assessing the statistical significance of the difference between two sample means‚ the construction of confidence intervals for the difference between two population means‚ and in linear regression analysis. Statistical significance is “measuring the likelihood that an event occurs by chance” (Statistical Assessment Service‚ 2000)

is .00081399‚ the ANOVA P-value is significantly less than alpha‚ and therefore there is strong evidence to reject the null hypothesis. Using the inferences about individual treatment means is appropriate‚ when we look at the health of the patients. It is reasonable to believe that all the patients are health or have the same health. The inferences in this test will be very limited. Extensions of this study or other analyses that could be helpful are limiting the age to smaller range‚ and using
