Answer 2

Answer C

Step-by-step explanation:

If one of the variables is measured on dichotomous nominal scale, such as gender and other is measured on interval or ratio scale, than we use point biserial correlation coefficient. It will measure our initial hypothesis that there is a connection between the time spent on the phone, talking to your mother with gender. Later, if we would want to conclude how strong is this connection, we would use regression analysis.
