In what specific way does Becker's model of time allocation differ from the simple-work leisure choice model?
Directions: Read the given situation, then state the possible consequence of an error made.
A quality control expert wants to test the null hypothesis that an imported solar panel is an effective source of energy.
1. Identify the Type I error in this context? What would be the possible consequence of committing the Type I error in this context?
a. They do not conclude that the solar panel is effective when it is not actually effective.
b. They do not conclude that the solar panel is effective when it is actually effective.
c. They conclude that the solar panel is effective when it is actually effective.
d. They conclude that the solar panel is effective when it is not actually effective.
8.) The energy required to punch a square from 30mm thick plate is 20KJ. If the ultimate strength of plate is 450Mpa, determine the maximum sides of square that can be punch.
Answer: S=24.69mm
How would education affect the probability that someone chooses not to participate in the labour force?
6.) The power required to shear a plate 60mm thick for 20sec is 8KW. If the ultimate strength of plate materials is 4oo Mpa, How wide should the plate be?
Answer: b= 222.22mm
5.) A plate 400mm wide and 0.03 mm thick with strength of 400Mpa is to shear. During shearing process a 1000mm mean diameter flywheel changes its speed from 220 to 200 rpm. Determine the weight of flywheel to be used.
Answer: W=61.34 KN
3.) During a punching process of 350 kg flywheel the speed varies 250 to 220 rpm with 1.2m mean diameter. Determine the kinetic energy needed.
Answer: 9.74 kN-m
A University has contracted you to develop their new student
records system. The normal tasks that the system performs are as follows: Enroll a student at the
university: A student provides his or her personal details (name, address, sex, date of birth),
along with the code of the course (e.g. Bachelor of Computer Science) in which he or she wishes
to enroll. A student record is created, and a unique student ID number is assigned to the student.
The system automatically enrolls the student in any core first-year subjects for the course.Do a thorough study of the problem – Identify Project scope, Objectives and Infrastructure.
Do Software Requirement Analysis – Describe the individual Phases/modules of the project and Identify deliverables. Identify functional and non-functional requirements.
Draw use case diagram(s) for the scenario.

1. A box contains 3 red,10 white, 5 blue and 2 green balls identical in mass and shape. Find the ratio of the number of green ball to the total numbers of balls.
2. The number of goals scored by a famous footballer per match in a tournament are:
0,2,1 0,1,3,2,1,1,1,4,1,1,2,1 2,0,0,1,1,1,1,0,2,0,0,2,1,1,3
From this data, find the ratio of the number of matches where the footballer scored more than two goals to the total number of matches.
1. The volume sample of gas is 750 mL at 60°C and 0.7 atm. At what temperature will the sample 1.75 L occupy under a pressure of 1.80 atm?
