3. [42.5 points] A large tech company is evaluating two programming languages. Twenty- four entry-level data scientists were asked to code a procedure. Twelve were randomly assigned to Programming Language 1, while the remaining twelve were assigned to Programming Language 2. Suppose you want to test whether the tech company should conclude Programming Language 1 is more inefficient. The following table shows the time required by each data scientist to code the procedure in seconds. Refer to Appendix A to...
