A researcher is interested in the extent to which years of practice among NPs predicts level of support for expanded prescription privileges, measured on a 10-point Likert scale. She finds that both variables, years of practice and level of support, are normally distributed. Her research question is: Does years of practice among NPs predict level of support for expanded prescription privileges? What is the appropriate statistic to address the research question?

Multiple linear regression, Simple linear regression, or One sample chi-square?
