Examine the results of (a) and (b) and comment on the usefulness of the frequency distribution in terms of temperature summarization capability. 2, A northwestern distribution company surveyed 53 of its midlevel managers. The survey obtained the ages of these managers, which later were organized into the frequency distribution shown.

An economy suffers from recession (unemployment). Using werds and graphs, answer the following questions: A. Words only (no need for graph): Will the Central Bank aim to increase or decrease the federal fund rate? Explain B. If the demand for reserves intersects their supply at the vertical portion, show how the Central Bank can achieve (or cannot achieve) its goal with regard the interest rate, using the open market sale. Explain C. If the demand for reserves intersects their supply at the horizontal portion, show how the Central Bank can achieve (or cannot achieve) its goal with regard the interest rate, using the open market purchase. Explain D. If the demand for reserves intersects their supply at the horizontal portion, show how the Central Bank can achieve (or cannot achieve) its goal with regard the interest rate, using the discount rate. Explain E. If the demand for reserves intersects their supply at the vertical portion, show how the Central Bank can achieve (or cannot achieve) its goal with regard the interest rate, using the open requires reserves ratio.

Implement the two versions of the maximum subarray sum we discussed in class: the brute force and the divide and conquer. Write your implementations in the skeleton file max_sub_sum/max_sub_sum.h. The file max_sub_sum/max_sub_sum.cpp is for your convenience it will not be used by autograding. Brute force (18pts) Implement the function template <typename Iter> int brute_max_sum(Iter start, Iter end) { return 0; } Keep the signature as it is, write the body. Divide and conquer (18pts) Implement the function int max_sub_sum(Iter start, Iter end) { return 0; } Keep the signature as it is, write the body.

Peak (18 pts) You are given an array A with n elements and the following properties: 1. Either it is sorted or 2. There exists an index k such that the array is sorted from 0 to k and sorted in reverse from k to n-1. In other words, there exists O<k<n-1 such that for all i<j<k and i>j>k we have A[i] <=A[j]<A[k] Below is the sequential implementation int peak(std::vector<int>& v, int start, ir for(int i=1;i<v.size()-1; if(v[i]>v[i-1]&& return -1; } Replace the above with a divide and conquer implementation. Write your implementations in the skeleton file peak/peak.h. The file peak/peak.cpp is for your convenience it will not be used by autograding.

Stock You are given an input array A with n positive elements. Each element is the value of a stock at that point (time). Assuming are given this future information you need to decide when to buy and sell the stock to make maximum profit (i.e. sell - buy). Write your implementations in the skeleton file stock/stock.h . The file stock/stock.cpp is for your convenience it will not be used by autograding. max_profit (18 pts) Implement, using divide and conquer, the function below which returns the maximum possible profit. template <typename Iter> typename Iter::value_type max_profit(Iter start, Iter end) { return e; } Buy and Sell (18 pts) Implement, using divide and conquer, the function below which returns a pair of iterators pointing to the buying/selling values respectively. template <typename Iter> std::pair<Iter, Iter> nax_profit_interval(Iter start, Iter end) { return std::make_pair(start, end); } Return the times (18 pts) Implement the function below which returns the indices of the buying selling values, given: 1.begin=iterator to the beginning of the container (e.g. vector), 1. start=iterator to buying element 2. end=iterator to selling element
