Two Means - Unknown, Unequal Variance: Videos & Practice Problems

A health researcher wants to compare daily water consumption between two groups of adults. For a sample of $50$ office workers, the mean daily water intake is $1.8$ $\text{liters}$. Assume the population standard deviation is $0.5$ $\text{liters}$. For a sample of $60$ outdoor workers, the mean daily water intake is $2.0$ $\text{liters}$, with a population standard deviation of $0.6$ $\text{liters}$.
At the $\alpha =0.01$ level of significance, can you reject the claim that the average water consumption is the same for office workers and outdoor workers?
