Answer the aftercited: The moderation sky for the month of July in Boston, Massachusetts is 73 degrees Fahrenheit. Plot the aftercited grounds, which personate the observed moderation sky in Boston balance the last 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 regular dispensation? Explain your forced.  What is an outlier? Are there any outliers in this dispensation? Explain your forced largely.  Using the aloft grounds, what is the presumption that the moderation conquer be balance 76 in any absorbed July?   Using the aloft grounds, what is the presumption that the moderation conquer be balance 80 in any absorbed July? A heatwave is defined as 3 or further days in a row delay a noble sky balance 90 degrees Fahrenheit. Absorbed the aftercited noble skys commemorative balance a end of 20 days, what is the presumption that there conquer be a heatwave in the instant 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 discover that 40% of customers alienation products online versus in the tangible fund precipitation.  Suppose that this concern produces 12 sales in a absorbed day  Does this condition fit the parameters for a binomial dispensation? Explain why or why not? Find the presumption of the 12 sales on a absorbed day correspondently 4 are made online Find the presumption of the 12 sales fewer than 6 are made online Find the presumption of the 12 sales further than 8 are made online Your own example: Choose a gang that you enjoy of-late seen in the tidings accordingly it is having some genus of height or defamation, and entire the aftercited:  Discuss the condition, and illustrate how the gang could use dispensations and presumption statistics to attain further encircling how the defamation could favor its concern.   If you were a concern analyst for the gang, what discovery would you nonproduction to do, and what peel of grounds would you nonproduction to garner to compose a dispensation?  Would this be a model, binomial, or Poisson dispensation?  Why?  List and examine at last 3 questions that you would nonproduction to compose probabilities for (e.g., What is the casualty that the gang loses 10% of its customers in the instant year?).   What would you expectation to attain from careful these probabilities?  Assuming that conspicuous administration does not see the compute in expending the space and capital indispensable to garner grounds to irritate, produce an reasoning (at last 100 words) convincing them that the price is indispensable and explaining some dangers the gang could aspect by not sharp what the grounds forebode.
