  1. Find a 95% confidence interval for the true proportion´┐Ż.
    We are 95% confident that the true proportion of all EXPERIMENTAL UNITS that have BINOMIAL CHARACTERSITIC falls between LOWER BOUND and UPPER BOUND.
  2. Practically interpret the value of the correlation coefficient relating y to x:
    An r of R-VALUE implies a STRONG/MODERATE/WEAK, POSITIVE/NEGATIVE linear relationship between X-VARIBALE and Y-VARIABLE.
  3. Give a practical interpretation of the 95% confidence interval for E(y) using the multiple regression model.
    We are 95% confident that the mean of Y-VARIABLE for all EXPERIMENTAL UNITS with X-VARIABLE=(X-VALUE)(UNITS OF MEASUREMENT) falls between LOWER CONFIDENCE INTERVAL and (UPPER CONFIDENCE INTERVAL)(UNITS OF MEASUREMENT)
