The following choices describe how to calculate degrees of freedom for different statistical tests. One of the descriptions is incorrect. Select the incorrect calculation.

Which of these statistical tests is the most appropriate to compare means between two groups that are assumed to be independent?

At December 31,2023, Day-Brite Inc.’s market value of equity was $8 billion and its total market value was $12 billion.  Day-Brite’s assumed statutory tax rate was 28%, its pretax borrowing rate was 4%, and its estimated market beta was .58.  Assume also that the expected risk-free rate is 2.5% and the expected market risk premium is 4%.  Estimate Day-Brite’s cost of equity capital

We shall consider the general method, employed by an adversary,  to prove that no algorithm can always decide a given problem X using less than M questions. For that purpose, the adversary maintains Q, and R_1 … R_M, such that : 1. X(Q) is true2. X(R_i) is false for all i \in 1 … M and such that after k questions from the algorithm:3. Q is consistent with all k answers from the adversary 4. for all i in 1 … M, except for at most k such, it holds that R_i is consistent with all k answers from the adversary.For each declaration from the algorithm, how should the adversary respond?

For the various knapsack problems, we have considered the greedy strategy G of first picking as much as allowed of the most precious item (the one with highest value/weight ratio), next picking as much as allowed of the second most precious item, etc, etc.  Match each version with the outcome guaranteed:
