The file london_weather.csv contains weather data for the years 1979 to 2020.

There appears to be some inconsistencies in this data, as there are rows for which the column max_temp contains an entry that is smaller than the corresponding entry in min_temp. Write a Python function wrong_temperature(year) that returns the number of days in a given year for which the column max_temp contains an entry that is smaller than the corresponding entry in the column min_temp.

8 An employee file contains records that show an employee's number, name, job code and pay code. The job codes and pay codes are three-digit codes that refer to cor- responding job descriptions and pay rates, as in the following tables: Job code Job description A80 Clerk A90 Word processor B30 Accountant B50 Programmer B70 Systems analyst C20 Engineer C40 Senior engineer D50 Manager Chapter 7: Array processing Pay code Pay rate 01 $9.00 02 $9.50 03 $12.00 04 $20.00 05 $23.50 06 $27.00 07 $33.00 Your program is to read the employee file, use the job code to retrieve the job description from the job table, use the pay code to retrieve the pay rate from the pay rate table, and print for each record the employee's number, name, job description and pay rate. At the end of the report, print the total number of employees.

The file ClassificationData.xlsx (Screenshot attached below) contains the following information about the top 25 MBA programs: percentage of applicants accepted, percentage of accepted applicants who enroll, mean GMAT score of enrollees, mean undergraduate GPA of enrollees, annual cost of school (for state schools, this is the cost for out-of-state students), percentage of students who are minorities, percentage of students who are non-U.S. residents, and mean starting salary of graduates (in thousands of dollars).Use these data to divide the top 25 schools into 4 clusters, usingfor example the K-Means clustering algorithm, and interpret your clusters. The method is explained in our textbook: Section 8.8 in the Fourth and Fifth Edition or Section 14.3 in the Sixth Edition. More precisely, use Evolutionary Solver to find 4 schools to be used as cluster centers and to assign all other schools to one of these cluster centers. Each school is then assigned to the nearest cluster center,…
