- 3. Multiple Choice
It is claimed that the average monthly income of chemical engineers last year was 27,900php. A random sample of 35 chemical engineers is selected and it is found out that the average monthly salary is 28,000. Using 0.01 level of significance, can it be concluded that there is an increase in the average monthly income of chemical engineers? Assume that the population standard deviation is 250.50.
Identify the null hypothesis.

- 9. Multiple ChoiceThe weight of the average 6th grade student's backpack (with books in it) is 18.4 lbs. The principal of the school thinks that the backpack does not weight 18.4 lbs. What is the null and alternate hypothesis?H0 = 18.4
Ha = 18.4H0 = 18.4
Ha > 18.4H0 = 18.4
Ha < 18.4H0 = 18.4
Ha ≠ 18.4 - 10. Multiple Choice
