Brine Shrimp Lab: Due Friday 9/9 through turnitin.com

Please Use the Following Guidelines to Write Up Your Brine Shrimp Lab.

• Question:  Is there a significant difference in hatching rate between brine shrimp hatched with 2% salt water and 3% salt water?

• Using the class data, do a t-test between 2% and 3% salt water.  Use the equation and show your work!
• Determine the number of degrees of freedom and look up the critical value.  
• Compare the t-value to the critical value and interpret the meaning.
• Discuss the quality of the data.  Is it consistent?  Is there enough of it?  
• Discuss at least 3 sources of uncertainty in the lab, being as specific as possible.  Include in your discussion whether you think these are major sources of uncertainty or fairly minor.
• Suggest at least 3 specific ways to improve the quality of the data.  In this case, each source of uncertainty should have a suggestion for improvement.

Submit through turnitin.com by Friday 9/9 at 3:20 pm.
