1.     Copy and paste this document from this step down into a word document.  Turn in this document with your typed answers following prompts (in at most 3 sentences each) following the protocol outlined below.  Leave a blank space below each question and type your reply below each. Put your name, my name and the name of the assignment at the top right hand corner of the page.   Submit a hard copy at the start of class on the due date.  Do NOT miss class or come to class late in order to work on this assignment. If you are late to class the lab will be marked as late. Do NOT type the answers to these questions into the body of your shared report on StatCrunch.

The answers to these questions must come directly from your histogram.  If you cannot use your histogram to answer them it means you made errors when you created the graph.

  1. What is the shape of your histograms? 

    Bell-shaped curves

  2. If you have made your frequency histogram correctly your fourth bin should span 6.5 to 8.5 with a 16 on top of the bar.  Interpret the number 16 and the interval from 6.5 to 8.5 in the context of this data.

    16 US states had an increase of 6.5 to 8.49 points in the number of individuals under 65 years

  3. If you have made your relative frequency histogram correctly your fourth bin should span 6.5 to 8.5 with a 0.32 on top of the bar.  Interpret the number 0.32 and the interval from 6.5 to 8.5 in the context of this data.

    32% of US states had an increase of 6.5 to 8.49 points in the number of individuals under 65 years

  4. What’s the percentage of states that had at least an 8.5 percentage point increase in their populations who have insurance in 2015 as compared to 2008?  What is the number of states who saw this large an increase with insurance?

    The percentage of states with at least an 8.5 percentage point increase was 30%

  5. Do you think the frequency or relative frequency histogram tells a better story of the data and why?

    I think that the relative frequency histogram tells a better story because it shows more than just the numbers unlike the frequency histogram

b, c and d are very poorly worded and do not convey the meaning of the data well
both histograms are completely wrong
