Suppose You Computed a 95% Confidence Interval for the Difference

question 4

Multiple Choice

Suppose you computed a 95% confidence interval for the difference in mean weight between two species of snakes in a large nature reserve (species #1 - species #2) , and your interval is -3.6 to 61.6 ounces.What can you conclude?

• A)You cannot say, even with 95% confidence that the observed difference in sample means represents a real difference in the population means.
• B)Because the interval extends so much further in the positive direction than the negative, the evidence suggests that species #1 weighs more than species #2 on average, but we can't say for sure.
• C)If we were willing to use 90% confidence, we could say that the observed difference in the sample means represents a real difference in the population means.
• D)All of the above.
