n) compute both a 95% confidence interval for the mean, e(y |x), and a 95% predic-
tion interval for y|x, where x denotes the vector of median (“typical”) covariate
values. report your code and output.
) which interval do you think an oncologist may use to diagnose a particular cancer
patient with typical symptoms?
) which interval do you think a cancer researcher may use to infer about the rela-
tionship of lpsa to symptoms of typical patients?

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why.a.) student.course.callnum = "csc230"; b.) cin > > student.name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student.name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist.course.credits = 3; j.) course = studenttype.course;

What is a loop? a. a collection of function definitions at the top of a program b. a line of code that defines a variable and assigns it a value c. a program that opens the turtle graphics window d. a block of code that repeats a specific number of times
