The Cars dataset has three columns giving the quality, machining angle, and machining speed of 18 cars. Write a program that performs the following tasks:
Load the data Cars. csv into a data frame called cars_df.
Subset the first userNum rows of the data frame into a new data frame.
Find and print the maximum values of each column in the subset.
Ex: If the input is:
5
the output is:
Quality 5
Speed 4
Angle 3
dtype: int64

Write a grading program for a class with the following grading policies: a. there are two quizzes, each graded on the basis of 10 points. b. there is one midterm exam and one final exam, each graded on the basis of 100 points. c. the final exam counts for 50% of the grade, the midterm counts for 25%, and the two quizzes together count for a total of 25%. (do not forget to normalize the quiz scores. they should be converted to a percentage before they are averaged in.) any grade of 90 or more is an a, any grade of 80 or more (but less than 90) is a b, any grade of 70 or more (but less than 80) is a c, any grade of 60 or more (but less than 70) is a d, and any grade below 60 is an f. the program will read in the student’s scores and output the student’s record, which consists of two quiz and two exam scores as well as the student’s average numeric score for the entire course and final letter grade. define and use a structure for the student reco
