Imagine a Series of Turbidity (Cloudiness) Measurements in the Water

question 53

Multiple Choice

Imagine a series of turbidity (cloudiness) measurements in the water from two different lakes. The measurements were taken over many different days (30 samples for each lake) and the figure shows the mean turbidity of those measurements along with bars representing 95% confidence intervals. What can we conclude about the appropriate null hypothesis and mean turbidity of the two lakes?
​
​

• A) Fail to reject the null hypothesis, we lack evidence that the turbidity differs between the lakes.
• B) Reject the null hypothesis, we have evidence that the turbidity differs between the lakes.
• C) Reject the null hypothesis, we lack evidence that the turbidity differs between the lakes.
• D) We can't really tell from this figure whether the null hypothesis will be rejected or not.
