Answer:
For this case since since they not want to differentiate between the campuses, so is good to use a simple random sampling or SRS, that is a procedure in order to select a sample of size n from a population of size N known, and each element of the population have the sample probability of being selected
So then the administrator can select a random sample of n students from all the campuses from the CSU University and obtain the distance from hometwon to campuses for the selected sample and then calculate the average and use this to inference.
Other possibility is use a systematic random sampling for example they can define a random number k and they can select 1 student each k individuals and then create a random sample of size n and calculate the average for this in order to do inference.
The convenience sampling is not too useful since is not a probabilistic method.
Step-by-step explanation:
For this case we can clasify this study as an enumerative study and inferential since they want to identify the average distance between the hometowns of students and their campuses.
For this case the sampling frame represent all the 23 campuses, and is known for the researcher,

Answer:
How far should he ride on each of the four days to reach his goal?
1st day: miles
2nd day: miles
3rd day: miles
4th day: miles
Step-by-step explanation: As the problem says, is the number of miles he rides on the first day. Let's start off with that.
1st day: miles
He want to ride 1.5 times as far as he rode the day before... no 1.5 more, but 1.5 <em>times</em> as far as he rode the day before; you would multiply 1.5 with the previous day's length.
2nd day:
Then you multiply to
to get the third day's.
3rd day:
4th day:
----------------------------
Phew! Gavin wants to ride a total of 65 miles over these four days, so if Gavin added all the miles of the four days, he should get 65...
1st+2nd+3rd+4th=65
Yes! Now that we've got the hard part done... substitute 8 for ever single .
1st day: miles
2nd day: miles
3rd day: miles
4th day: miles
-------------------------
Checking my answer:
Just add the miles!
