Answer the following: The beggarly temperature for the ages of July in Boston, Massachusetts is 73 degrees Fahrenheit. Plot the afterward data, which represent the empiric beggarly temperature in Boston over the aftermost 20 years: 1998 72 1999 69 2000 78 2001 70 2002 67 2003 74 2004 73 2005 65 2006 77 2007 71 2008 75 2009 68 2010 72 2011 77 2012 65 2013 79 2014 77 2015 78 2016 72 2017 74 Is this a accustomed distribution? Explain your reasoning.  What is an outlier? Are there any outliers in this distribution? Explain your acumen fully.  Using the aloft data, what is the anticipation that the beggarly will be over 76 in any accustomed July?   Using the aloft data, what is the anticipation that the beggarly will be over 80 in any accustomed July? A heatwave is authentic as 3 or added canicule in a row with a aerial temperature over 90 degrees Fahrenheit. Accustomed the afterward aerial temperatures recorded over a aeon of 20 days, what is the anticipation that there will be a heatwave in the abutting 10 days? Day 1 93 Day 2 88 Day 3 91 Day 4 86 Day 5 92 Day 6 91 Day 7 90 Day 8 88 Day 9 85 Day 10 91 Day 11 84 Day 12 86 Day 13 85 Day 14 90 Day 15 92 Day 16 89 Day 17 88 Day 18 90 Day 19 88 Day 20 90 Customer surveys acknowledge that 40% of barter acquirement articles online against in the concrete abundance location.  Suppose that this business makes 12 sales in a accustomed day  Does this bearings fit the ambit for a binomial distribution? Explain why or why not? Find the anticipation of the 12 sales on a accustomed day absolutely 4 are fabricated online Find the anticipation of the 12 sales beneath than 6 are fabricated online Find the anticipation of the 12 sales added than 8 are fabricated online Your own example: Choose a aggregation that you accept afresh apparent in the account because it is accepting some array of botheration or scandal, and complete the following:  Discuss the situation, and call how the aggregation could use distributions and anticipation statistics to apprentice added about how the aspersion could affect its business.   If you were a business analyst for the company, what analysis would you appetite to do, and what affectionate of abstracts would you appetite to aggregate to actualize a distribution?  Would this be a standard, binomial, or Poisson distribution?  Why?  List and altercate at atomic 3 questions that you would appetite to actualize probabilities for (e.g., What is the adventitious that the aggregation loses 10% of its barter in the abutting year?).   What would you achievement to apprentice from artful these probabilities?  Assuming that high administration does not see the amount in expending the time and money all-important to aggregate abstracts to analyze, accomplish an altercation (at atomic 100 words) acceptable them that the amount is all-important and answer some dangers the aggregation could face by not alive what the abstracts predict.
