Use the appropriate significance level * State the initial and alternative hypothesis. * Find the test statistic and the P-value. You must first write the formula for the test statistic and then substitute your appropriate numbers. * Draw a conclusion in context of the situation. Your conclusion should include both the formal language as well as an informal explanation. * Find a correlation between height and shoe size. * Create a scatterplot of the data. Height is x-axis and Shoe size is y-axis. Attach your scatterplot to the end of this document. * Find the linear correlation coefficient. What does this tell you about your data? * Write the equation of the regression line and use it to predict the shoe size of a person that is 68 inches tall.
