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

(a) To compute P≤χ2 17 with 12 degrees of freedom, you would need to use the cumulative distribution function (CDF) for the chi-square distribution. In the ALEKS calculator, you would select the chi-square distribution, input 12 for the degrees of freedom, and 17 for the value of χ2. The calculator will then give you the probability P≤χ2 17.

(b) To find k such that Pχ2 k = 0.025, you would need to use the inverse of the cumulative distribution function (also known as the quantile function or the percent-point function). In the ALEKS calculator, you would select the chi-square distribution, input 12 for the degrees of freedom, and 0.975 for the probability (because 1 - 0.025 = 0.975). The calculator will then give you the value of k.

Remember to round your answers to the required number of decimal places.
