Document Summary
Know how to calculate a sample regression problem(get from phone) Degrees of freedom: is the number of independent pieces of information that went into calculating the estimate. Need to know how to calculate from table. A 0. 6 correlation is between large and very large. Get answers from phone (solve for height) This answer is not accurate because it can be predicted within standard error. But chances are the persons whose height you are predicting is not exactly 179. 69cm (thy will not fall directly on the regression line) So to be more confident (68%) with your prediction you can say their height is +- 179. 69. If a 1 sample t-test the degrees of freedom is the sample size minus 1. The degrees of freedom in a independent t-test is the sum of each sample minus 1. The smaller the alpha the greater probability.
