Third Week of School

• Tues 9/12/17:  Go over how to show work using the standard deviation and t-test formula.  Calculate the standard deviation and t-test for the class brine shrimp data and determine whether the salinity (3 or 5% salt water) had a significant impact on the hatching rate.  Show work for this on the back of the statistics packet.  As a class we will learn how to do a histogram and then each student will make one using the vole data from the statistics packet.  The rest of the time will be for working on the statistics packet.  When you are done, turn it in.  Get the TI-84 and Brine Shrimp lab hand-out checked off.  Statistics Packet should be turned in before the end of class or at the beginning of class on Thursday 9/14.
• Thurs 9/14/17:  Review statistics material.  We will take a quiz on it on Mon 9/18.  Begin Cells Unit by starting Introduction to Cells Worksheet.  Homework:  prepare for the quiz and start reading 1.1 in the text.
