An author argues that more American-born baseball players have birth dates in the months immediately following July 31 because that was the age cutoff date for nonschool baseball leagues. The table below lists months of births for a sample of American-born baseball players and foreign-born baseball players. Using a 0.01 significance level, is there sufficient evidence to warrant rejection of the claim that months of births of baseball players are independent of whether they are born in America? Do the data appear to support the author's claim?

Consider the following database schema for a BOOKSTORE database:
The Books relation stores information about books sold by the bookstore. Note that bookid is the primary key. An example tuple is as follows:
(105, 'JAVA PROGRAMMING', 'JOHN DOE', 2001)
The Customers relation stores information about the customers of the bookstore. Note that customerid is the primary key. An example tuple is as follows:
(210, 'JOHN SMITH', '[email protected]')
The Purchases relation stores information about the customer purchases of books. Note that customerid and bookid form the primary key. An example tuple is as follows:
(210, 105, 2002), indicating that 'JOHN SMITH' with customerid 210 purchased the 'JAVA PROGRAMMING' book with bookid 105 in the year 2002.
The Reviews relation stores information about the customer reviews/ratings of the books. The ratings field refers to the number of "stars" given to the book. Note that customerid and bookid form the primary key. An example tuple is as follows:
(210, 105, 3), indicating that 'JOHN SMITH' with customerid 210 gave a 3-star rating to the 'JAVA PROGRAMMING' book with bookid 105.
The Pricing relation stores information about the price of the various books sold by the bookstore. Note that the same book can be available in multiple formats at possibly different prices. The price field refers to the number of dollars. For instance a $25 purchase will have a price field of 25. Note that the bookid and format fields form the primary key for the relation. An example tuple is as follows:
(105, 'AUDIO', 25), indicating that the 'JAVA PROGRAMMING' book with bookid 105 is available in the audio format for $25.
Given the above schema, write queries for the following:
