You will implement and test the sequence class using an array to store the sequence's items in C++. sequence1.h: The header file for the sequence class. Actually, you don't have to write much of this file. Start with the sequence1.h header file provided and add your name and other information at the top. Also, decide on appropriate private member variables, and declare these in the sequence class definition at the bottom of the header file. If some of your member functions are implemented as inline functions, then you may put those implementations in this file too. 2. sequence1.cxx: The implementation file for this first sequence class. You will write all of this file, which will have the implementations of all the sequence's member functions. // FILE: sequence1.h // CLASS PROVIDED: sequence (part of the namespace main_savitch_3) // There is no implementation file provided for this class since it is // an exercise from Section 3.2 of "Data Structures and Other Objects Using C++" // // TYPEDEFS and MEMBER CONSTANTS for the sequence class: // typedef ____ value_type // sequence::value_type is the data type of the items in the sequence. It // may be any of the C++ built-in types (int, char, etc.), or a class with a // default constructor, an assignment operator, and a copy constructor. // // typedef ____ size_type // sequence::size_type is the data type of any variable that keeps track of // how many items are in a sequence. // // static const size_type CAPACITY = _____ // sequence::CAPACITY is the maximum number of items that a sequence can hold. // // CONSTRUCTOR for the sequence class: // sequence( ) // Postcondition: The sequence has been initialized as an empty sequence. // // MODIFICATION MEMBER FUNCTIONS for the sequence class: // void start( ) // Postcondition: The first item on the sequence becomes the current item // (but if the sequence is empty, then there is no current item). // // void advance( ) // Precondition: is_item returns true. // Postcondition: If the current item was already the last item in the // sequence, then there is no longer any current item. Otherwise, the new // current item is the item immediately after the original current item. // // void insert(const value_type& entry) // Precondition: size( ) < CAPACITY. // Postcondition: A new copy of entry has been inserted in the sequence // before the current item. If there was no current item, then the new entry // has been inserted at the front of the sequence. In either case, the newly // inserted item is now the current item of the sequence. // // void attach(const value_type& entry) // Precondition: size( ) < CAPACITY. // Postcondition: A new copy of entry has been inserted in the sequence after // the current item. If there was no current item, then the new entry has // been attached to the end of the sequence. In either case, the newly // inserted item is now the current item of the sequence. // // void remove_current( ) // Precondition: is_item returns true. // Postcondition: The current item has been removed from the sequence, and the // item after this (if there is one) is now the new current item. // // CONSTANT MEMBER FUNCTIONS for the sequence class: // size_type size( ) const // Postcondition: The return value is the number of items in the sequence. // // bool is_item( ) const // Postcondition: A true return value indicates that there is a valid // "current" item that may be retrieved by activating the current // member function (listed below). A false return value indicates that // there is no valid current item. // // value_type current( ) const // Precondition: is_item( ) returns true. // Postcondition: The item returned is the current item in the sequence. // // VALUE SEMANTICS for the sequence class: // Assignments and the copy constructor may be used with sequence objects. #ifndef MAIN_SAVITCH_SEQUENCE_H #define MAIN_SAVITCH_SEQUENCE_H #include // Provides size_t namespace main_savitch_3 { class sequence { public: // TYPEDEFS and MEMBER CONSTANTS typedef double value_type; typedef std::size_t size_type; static const size_type CAPACITY = 30; // CONSTRUCTOR sequence( ); // MODIFICATION MEMBER FUNCTIONS void start( ); void advance( ); void insert(const value_type& entry); void attach(const value_type& entry); void remove_current( ); // CONSTANT MEMBER FUNCTIONS size_type size( ) const; bool is_item( ) const; value_type current( ) const; private: value_type data[CAPACITY]; size_type used; size_type current_index; }; } #endif

Each of the following statements corresponds (somewhat naturally) to a statistical hypothesis. For each statement, decide

If it involves one or more populations; one or more variables. [No answer needed.]

The population(s) and the variable(s) involved.

The form of the test.

Single parameter

Two parameter or multiple parameter—always the same parameter for multiple populations (or possibly multiple variables)

Single distribution

Two distributions or multiple distributions—either two different variables, or the same variable for multiple populations

Independence

Note with measures of association will have one parameter (g, r, b) with a pair of populations

If the hypothesis is on one or more parameters, give

The parameter(s) involved.

The Null and the Alternate hypotheses. or

Whether the hypothesis test is one or two-sided. or

If the hypothesis is on one or more distributions, give

The Null and the Alternate hypotheses.

Why don’t we need to specify whether one-sided or two-sided?

Additional Requirements

1.The name of your source code fileshould be ProbEst.py All your code should be within a single file.

2.You cannot import any package except for pandas.You need to use the pandas DataFrame object for storing data

Requirements Y ou are to create a program in Python that performs the following: 1. Asks the user for the number of cars (i.e. data instances) . 2. F or each car , ask s the user to enter the following fields: make, model , type (coupe, sedan, SUV), rating (A, B, C, D, or F) . Save the feature values for each car in a DataFrame object. 3. Display s the resulting DataFrame 4. Compute s the probability of each rating and output s to the screen. 5. For each type , compute s the conditional probability of that type, given each of the ratings: 6. Display s the conditional probabilities to the screen.

Melanie is employed full-time as an accountant for a national hardware chain. She also has recently started a private consulting practice, which provides tax advice and financial planning to the general public. For this purpose, she maintains an office in her home. Expenses relating to her home for 2020 are as follows:

Melanie's residence cost $397,000 (excluding land) and has living space of 2,000 square feet, of which 35% (700 square feet) is devoted to business. The office was placed in service in February 2019, and under the Regular Method, Melanie had an unused office in the home deduction of $300 for 2019.
