Refer back to Example 13.3 in which the simple linear regression model was fit to data on x =proportion who judged candidate A as more competent and y = vote difference proportion. For the purpose of estimating β as accurately as possible, would it have been preferable to have observations with x values .05, .1, .2, .3, .4, .5, .6, .7, .8, .9, .95 and .98? Explain your reasoning.
