I want to take a survey of students currently enrolled in my statistics course. There are 250 of them, so I number them from 001
emmasim [6.3K]

Answer:

174, 095, 148, 064, 239

Step-by-step explanation:

This is a "simple random sample" problem in which we randomly select a sample from a larger population therefore everyone has same probability of being selected.

Total students: 250

Labeled as 001, 002, 003,.....250

The generated random number table is:

69041 65817 87174 09514 8174 06423 93758 23612 17894

Now we have to arrange/sort this random number table in groups of three numbers.

690, 416, 581, 787, 174, 095, 148, 174, 064, 239, 375, 823, 612, 178, 94

Now we have to select first 5 distinct numbers in the range of 001 to 250

The first four numbers (690, 416, 581, 787) are out of range so ignore them.

Next we find our first three numbers (174, 095, 148)

Next we have number (174) again that we have already selected so ignore it.

Next we find our fourth and fifth number (064, 239)

We are done with selecting 5 numbers and these are:

174, 095, 148, 064, 239

What are your best descriptions of both positive and negative experiences that influence how you feel about learning math?
andriy [413]
POSITIVE: Well, I suppose you'll actually use math relatively more often in life (compared to science)
Also, in math, if you get a question correct, it will always be correct, unlike English or other languages, if the teacher thinks your writing isn't good, she can give you a bad grade. In English, the grades you get are often subject to the teacher's moods/ opinions of you as a student.
NEGATIVE: Well, it gets boring.
