Explain how to determine the mean of a variable. What is quantitative data that can take on any value in a given interval called? What is the 95% prediction interval for Y when X1 is equal to 40 (in 000's)? Define an array and provide an example. ...
Parameter In C++, pointer arguments are used for both scalar data and array data. To use a pointer as an array, MATLAB®needs dimension information to safely convert the array between C++ and MATLAB. Theparameter helps you specify the dimensions for the pointer. ...
