Your
initial post should be 75-150 words in length. Watch this video: https://www.youtube.com/watch?v=tFWsuO9f74o What is a confidence interval?What are some factors that affect the size of a confidence interval?In the discussion for week 4,
you rolled a pair of dice 10 times and calculated the average sum of
your rolls. Then you did the same thing with 20 rolls. Use your
results from the week 4 discussion for the average of 10 rolls and for
the average of 20 rolls to construct a 95% confidence interval for the
true mean of the sum of a pair of dice (assume σ = 2.41). What do you notice about the
length of the interval for the mean of 10 rolls versus the mean of 20
rolls? Did you expect this? Why or why not?Using your mean for 20 rolls,
calculate the 90% confidence interval. Explain its size as compared to
the 95% confidence interval for 20 rolls.**Note below are the average sum of my rolls from my discussion for week 4. This information is needed to help answer question above.**When rolling the dice 10 times, the results are shown below: 3+2=5 5+5=10 1+1=2 1+5=6 3+6=9 4+1=5 1+1=2 2+6=8 1+5=6 3+2=5 (Total avg: 58/10=5.8) When rolling the dice 20 times, the results were as shown below: 1+2=3 1+3=4 6+4=10 2+1=3 6+1=7 1+3=4 6+5=11 1+6=7 1+2=3 4+1=5 6+2=8 2+2=4 3+2=5 3+3=6 1+6=7 5+2=7 2+1=3 3+3=6 2+2=4 1+5=6 (Total avg: 113/20=5.65)Please provide original work.
