2. One of the undersecretaries of the Department of Labor and Employment (DOLE) claims that the average salary of a civil engineer is Php 18,000. A sample of 19 civil engineer's salary has a mean of Php 17,350 and a standard deviation of Php 1,230. Is there enough evidence to reject the undersecretary's claim at a = 0.01?
Solution:
step 1: null and alternative hypothesis
H0:__________
H1:__________
step 2: Significance level a =__________
step 3: test statistic
step 4: decision rule
step 5: decision

What is the kinetic energy of a 1,500-kg car traveling at 110 kph if the car can reach this velocity in 12 seconds starting from rest? What is the power output of the engine in HP?
Write a program that initially requests
the user to enter the number of students
in a class. The program then proceeds to request the user to enter the marks (double) of these
students; these are to be inserted into an
array. Once all the marks have been entered,
your program shall have and use the below
functions
1. public static double sum(int [] array). Calculate & return sum of all marks.
2. Public static double[] sort(int []
array). Sort array containing marks.
3. public static double max(int []
array). Return highest mark.
4. public static double min(int [] array). Return lowest mark.
