A random sample of patient records from a large medical facility were taken and subjects were classified by smoking status and cholesterol levels. The results are summarized in the table with observed counts next to expected values in parentheses followed by the Chi-square component for each cell in brackets. Find the value of Chi-square, the degrees of freedom, and the P-value for this test and list them in the space provided. 

Problem 1: Hash Practice (6 points) (a) Insert integer keys A = in order into a hash table of size 7 using the hash function \(h(k) = (10k + 4) \mod 7\). Each slot of the hash table stores a linked list of the keys hashing to that slot, with later insertions being appended to the end of the list. Draw a picture of the hash table after all keys have been inserted. (3 points) (b) Suppose the hash function were instead \(h(k) = (10 k + 4) \mod c\) for some positive integer \(c\). Find the smallest value of \(c\) such that no collisions occur when inserting the keys from A. (3 points) Hint: By the pigeonhole principle, at least one collision occurs for \(c < 7\). Problem 2: Open Address Hashing (4 points) Consider an open-address hash table with a size of \(m = 16\). A hashing function maps keys to a random slot in the table. There are no deletions. Give the upper bounds on the expected number of probes for a successful and unsuccessful search when the load factor is \(\alpha = 1/2\). Note: You do not need to calculate the final numerical value if the answer involves a function like \(\ln\).

Problem 1: Graph Practice (10 points) Consider the directed graph shown below and answer the following questions. (a) Write down the adjacency list representation of the graph, where a dictionary maps each vertex v to its adjacency list Adj, which contains v’s outgoing neighbors listed in alphabetical order. (2 points) (b) Run both BFS and DFS on the graph, starting from node A. While performing each search, visit the outgoing neighbors of a vertex in alphabetical order. For each search, list vertices in the order in which they were first visited. (4 points) (c) It is possible to remove a single edge from the graph to make it a DAG. State every edge with this property, and for each, state a topological sort order of the resulting DAG.
