The data below represents the population of a certain country every 10 years for the years? 1900-2000. How do I determine the? least-squares regression? equation, treating year as the explanatory variable? If a normal probability plot of the residuals indicates that the residuals are approximately normally distributed, how do I test whether a linear relation exists between year and population using the α=0.01 level of significance stating the null and alternative hypotheses and then determine the? P-value of this hypothesis test?
