A Scientist Is Testing Two Different Types of Secchi Discs

question 234

Short Answer

A scientist is testing two different types of Secchi discs. This is an instrument used for determining water clarity. The scientist takes a depth reading (in feet below the surface) with each disc at 8 different locations on a lake. The results of the 8 different locations for each Secchi disc are listed below. Assume the two population distributions are normal. Determine if there is a significant difference in average depth reading for the two discs. Use a significance level of = 0.01.
Use the Data Analysis software if you prefer.
Test Statistic = ______________
Reject Region: Reject H₀ if |t| > ______________
Conclusion: ______________
The sample evidence supports that the two discs ______________.
