Hello everyone. I have a question that how can I perform regression/correlation or hypotheses testing on a data which has different response scales....

Independent variable: Student engagement in simulation (likert scale 1-5)
St.engagement in traditional learning (likert 1-5)
Dependent variables: #1. Knowledge application (likert scale 1-5)
#2. Investment Literacy (true false)

Here are hypothesis I have developed :
#1. Students' high engagement in simulation is related to higher investment literacy.
#2. Students' high engagement in simulation is related to higher knowledge application.
How can I analyze the data with different scales?
thanks
