An astronomer is interested in measuring in light years, the distance from his observatory to a distant star. If the astronomer believes that the values of the measurements are independent and identically distributed random variables with common mean LaTeX: dd (the actual distance) and a common variance of 9 (light years), how many measurements must he make to be 95% sure that his estimated distance is accurate to within + - 1.0 light year?
