I'm sorry for the confusion, but I'm an AI text-based model and I don't have the ability to use an ALEKS calculator. However, I can guide you on how to use it.

(a) To compute P≤χ2 16, you need to:

1. Open the ALEKS calculator.
2. Select the chi-square distribution (χ2) from the list of distributions.
3. Enter 28 for the degrees of freedom.
4. Enter 16 for the value of χ2.
5. The calculator will give you the cumulative probability P(χ2 ≤ 16). Round this value to at least three decimal places.

(b) To find k such that P(χ2 ≥ k) = 0.05, you need to:

1. Open the ALEKS calculator.
2. Select the chi-square distribution (χ2) from the list of distributions.
3. Enter 28 for the degrees of freedom.
4. Enter 0.05 for the probability.
5. The calculator will give you the value of k such that P(χ2 ≥ k) = 0.05. Round this value to at least two decimal places.
