Hello!
To take a sample to estimate the mean height of all students at a university and that the value you reach is statistically valid you need the sampling method to be random and representative of the whole population, in this example, all university students.
a. Measure the heights of 50 students found in the gym during basketball intramurals.
This method is not the best because you would be sampling only basketball players leaving all other students of the university outside, i.e. your sample will not be representative of all the students, just the ones that play basketball.
b. Measure the heights of all engineering majors.
This method is not good, the sample only represents engineering mayors meaning that it does not include the students of any other subjects.
c. Measure the heights of the students selected by choosing the first name on each page of the campus phone book.
With this method you choose students regardless of the sport or major they're are taking, it is more representative of the population of university students, of the three options, this is the best one.
I hope it helps!
Disclaimer- this is all assuming that "semi monthly" means twice a month. if it doesn't, ignore this answer
A- if semi monthly is half a month, then 4 times 2 is 8, and 8 times 12 is 96,000.
B- If there are 4 weeks in a month and 4000$ accounts for half of that pay, then the weekly pay is 2000, making the bi-weekly pay 1000.
C- The monthly pay is 8,000$ because 4,000 x 2 is 8,000
D- The weekly pay is 2,000$ because the monthly pay is 8,000$ and there are 4 weeks in a month
E- I do not know the hours at this job and therefore cannot answer this
