In an experiment, one group of research participants is given 10 pages of material to proofread for errors. another group proofreads the same material on a computer screen. the dependent variable is the number of errors detected in a 5- minute period. a .05 signicance (alpha) level is used to evaluate the results. a. what statistical test would you use? b. what is the null hypothesis? the research hypothesis? c. what is the type i error? the type ii error? d. what is the probability of making a type i error?

Define a class named movie. include private fields for the title,year, and name of the director. include three public functions withprototypes void movie: : settitle(cstring); , voidmovie: : setyear(int); , void movie: : setdirector(string); . includeanother function that displays all the information about a movie.write a main() function that declares a movie object namedmyfavoritemovie. set and display the object's fields.this is what i have but know its wrong since it will notcompile: #include#includeusing namespace std; //class declarationclass movie{private: string movietitle ; string movieyear; string directorname; public: void settitle(string title); void setyear(string year); void setdirector(string director); void displayinfo(); }; //class implementationvoid movie: : settitle(string title){ movietitle = title; cout< < "what is the title of themovie?
