Week 7 Lab prep

Objective: Discuss and analyze results of last lab's experiment, work on draft of Final Report due by lab this week

Date: May 12, 2014

Today's meeting:

• Chi-Square Goodness of Fit test, testing

• Ho: percent change in sample mass is approximately equal to the expected values
• Ha: at least one of the observed percent change in sample mass differs from the expected value
• Use significance level 5% (alpha = 0.05)
• Results:
• From the experiment, there is sufficient evidence to support the claim that hair absorbs 2x its mass in water, 10x its mass in an oil-water mixture, and 12x its mass in oil!!!
• Q's for Dr. Allen (to ask on Thursday)
  - Is appropriate for the presentation to incorporate a little humor (especially puns)?
       --> This problem just got hairy!
       --> It's about to get mesh-y!
       --> So... wat'er we waiting for??
  - Is it possible to get a projector, so we won't need to prepare a larger scale demo?
  
  

For next time:

• Finish individual report parts by Tuesday night
• Finish editing and submit on Wednesday
• Bring laptops to create PowerPoint for week 10's final presentation
