1. The parameter is average time in years.

H0:μ=5H_0:\mu=5

Ha:μ5H_a:\mu\not=5

This corresponds to a two-tailed (non directional) test.

The level of significance is α=0.05.\alpha=0.05.


2. The parameter is the mean annual income.

H0:μ500000H_0:\mu\le500000

Ha:μ>500000H_a:\mu>500000

This corresponds to a right-tailed one-tailed (directional) test.

The level of significance is α=0.05.\alpha=0.05.
