Weekend HW!

Due Monday: 2 assignments!
*These will be checked/graded as 2 separate HW assignments

1.) Please complete the "middle right slide" you have--it's the question below. You can do this in your notes!

• This is something we haven't seen in class--your job is to figure it out! Try SOMETHING! Blank = 0 on HW!
• The Question: (if you don't have the slide just write this in your notes)

• Here's a little visual that might help you in your approach to the question above....

2.) Please complete the "Understanding CI Formula" worksheet provided in class Thursday or linked below. 

• Understanding CI Formula HW (Click Me...seriously....do it!)
• For the first part of 7 you're just showing the "math work"--the calculator screen and formula, you don't have to interpret or check conditions
• For the second part of 7: "Does the 99% confidence interval provide evidence that the state will legalize sports betting? Why or why not?"....
• Consider your interval....
• Now think about this: what % of people would have to vote in favor of sports betting for it to be legalized?
• Does our interval definitively suggest that the % who support sports gambling meets that criteria?
• This is not a long explanation--one sentence here.....here's a template:
• "Yes/no the 99% CI does/does not provide evidence that the state will legalize sports betting because......."
• ALWAYS CHECK YOUR ANSWERS!
• 1.) 0.0503 or 5.03% = ME
• 2.) n = 812 --> D (always round/go up)
• 3.) z* = 2.3295, closest to 98% confidence
• 4.) C
• 5.) n = 291 (always round up)
• 6.) ME = 0.03588 or 3.588%
• 7.) 1 Prop Z Int = 49.124% to 56.876%
