For the employees who left the company before 3 years, what is an appropriate test of hypothesis to determine if the mean tenure of such employees equals 18 months in the population? One sample t test Paired samples t test Independent samples t test None of the above

Here one sample t test would be the appropriate test of hypothesis to determine if the mean tenure of employees equals 18 months in the population.
