Chapter 8, Problem 1P

For this question, use this data: myFunc = function (x, y = 2) {z = 7 Z+x^2+y } What is the output of myFunc(2)? O 13. O An error, y is undefined. O Nothing, we have to assign it as a vari O 9.

a medical test has some probability of being positive if the patient has the disease (hasPos) and another probability of testing positive if the person does not have the disease (notHasPos).  a random member of the entire population has a real problem of having the disease (actual incidence).  Based on the attached information what does the result of the function?

myFunc = function (x, y = 2) {z = 7 } z+x^2+y Assuming that this was the first thing entered in a new R session, if the next command entered is z+1, what is the output? O 8. ● An error, z does not exist. O 10. O 7.
