Each box of Healthy Crunch breakfast cereal contains a coupon entitling you to a free package of garden seeds. At the Healthy Crunch home office, they use the weight of incoming mail to determine how many of their employees are to be assigned to collecting coupons and mailing out seed packages on a given day. (Healthy Crunch has a policy of answering all its mail on the day it is received.) If the answer is a whole number, write a whole number. If it has one decimal place, write one decimal place. Otherwise, round off to two decimal places. If the answer is greater than 999, put a comma. a. Solve for Σx = Blank 1 b. Solve for Σy = Blank 2 c. Solve for Σx2 = Blank 3 d. Solve for Σy2 = Blank 4 e. Solve for Σxy = Blank 5 f. Solve for Pearson's r = Blank 6 g. Solve for the variance = Blank 7 h. Solve for the slope of the simple linear regression line = Blank 8 i. Solve for the y-intercept of the simple linear regression line = Blank 9 j. If the weight of the incoming mail is 30 lb, what would most likely be the number of employees required to process the mail in one working day (use the rounded values for slope and intercept, and round off your answer to the nearest whole number) = Blank 10 Let x = weight of incoming mail and y = number of employees required to process the mail in one working day. A random sample of 8 days gave the following data: x (lb) 11 20 16 6 12 18 23 25 y ( no. of employees) 6 10 9 5 8 14 13 16
Control structures
Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.
Switch Statement
The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.
