Chapter 2, Problem 6P

The following algorithm is designed to determine a grade for a course that consists of quizzes, homework, and a final exam:

Step 1: Input course number and name.

Step 2: Input weighting factors for quizzes ( WQ ) , homework ( WH ) , and the final exam ( WF ) .

Step 3: Input quiz grades and determine an average quiz grade ( AQ ) .

Step 4: Input homework grades and determine an average homework grade ( AH ) .

Step 5: If this course has a final grade, continue to step 6. If not, go to step 9.

Step 6: Input final exam grade ( FE ) .

Step 7: Determine average grade AG according to

AG = WQ × AQ + WH × AH + WF × FE WQ + WH + WF × 100 %

Step 8: Go to step 10.

Step 9: Determine average grade AG according to

AG = WQ × AQ + WH × AH WQ + WH × 100 %

Step 10: Print out course number, name, and average grade.

Step 11: Terminate computation.

(a) Write well-structured pseudocode to implement this algorithm.

(b) Write, debug, and document a structured computer program based on this algorithm. Testitusingthefollowingdatato calculate a grade without the final exam and a grade with the final exam: WQ = 30; WH = 40; WF = 30 ; quizzes = 98, 95, 90, 60, 99 ; homework = 98 ,   95 ,   86 ,   100 ,   100 ,   77 ; and final exam = 91 .

In the provided table, the education information and incomes of 73,736 people are given. The rows are labeled with education status and the columns are labeled with income range. The total of all entries in each row gives the total number of people with the corresponding education status and similarly, the total of all entries of a particular column gives the number of people with the corresponding income range. Please answer subpart 4 and 5.
Covid-19, making malls in Singapore begin to limit the number of visitors and time of visits. One of the marketing directors of a large department store wanted to estimate the average number of customers who entered the store every five minutes. He randomly selects a sample and watches the customer for five minutes. He got the numbers 74, 32, 41, 47, 56, 80, 45, 29, 32, and 78. Then the director asked the analyst to count the number of arrivals at the store. The analyst assumes the number of arrivals is normally distributed. Using this data and a 95% confidence interval, calculate the estimated five-minute average value inside the department store! What is the benefit of estimating the estimated value in this case (analyze the answers you have obtained)?
