Researchers at the Mayo Clinic found a significant association between hospital sound levels and patient healing (louder hospital sound level is associated with slower healing). Based on these findings, a new hospital installed a new flooring that is supposed to reduce the noise level in hospital corridors. Using α = 0.01, did the variance of noise level decrease? (use both methods) Problem 4: Mayors of nine communities started a watch program to reduce vandalism. The number of vandalism incidents before and after starting the watch program was collected for each community. Does the data collected show that the watch program was effective? (use both methods)

4. Write out the pseudocode for when Merge-Sort is stable based on the information given below:

Comparision Based Stable Sorts such as Merge Sort maintain stability by ensuring that Element A[ j ] comes before A[ i ] if and only if A[ j ] < A[ i ], here i, j are indices and i < j. The relative order is preserved if A[ i ] comes before A[ j ].

Mergesort is stable, provided its implementation employs the comparison ≤ in merging. Indeed, assume that we have two elements of the same value in positions i and j, i < j, in a subarray before its two (sorted) halves are merged. If these two elements are in the same half of the subarray, their relative ordering will stay the same after the merging because the elements of the same half are processed by the merging operation in the FIFO fashion. Consider now the case when A[ i ] is in the first half while A[ j ] is in the second half. A[ j ] is placed into the new array either after the first half becomes empty (and, hence, A[ i ] has been already copied into the new array) or after being compared with some key k > A[ j ] of the first half. In the latter case, since the first half is sorted before the merging begins, A[ i ] = A[ j ] < k cannot be among the unprocessed elements of the first half. Hence, by the time of this comparison, A[ i ] has been already copied into the new array and therefore will precede A[ j ] after the merging operation is completed.

On 3/31/2020, Company ABC released its quarterly report, showing the sales in the first quarter had tumbled 30% as pandemic hit. However, the stock price for company ABC rose by 3% (instead of fell by 3%) after the report is released. Does this mean a failure of the Market Efficient Theory? please write equations and solve step by step
