A. B. The 95% confidence interval is _____ <μd< _____. (Round to two decimal places as needed.) What does the confidence interval suggest about farmer Joe's claim that type 1 seed is better than type 2 seed? A. Because the confidence interval only includes positive values and does not include zero, there is not sufficient evidence to support farmer Joe's claim. B. Because the confidence interval includes zero, there is sufficient evidence to support farmer Joe's claim. C. Because the...
