Answer:
B
Step-by-step explanation:
Yes, because the sample size is at least 30, and we have a random sample.
We have our sample size to be 33% of the student = 33 student (approx)
- According to conditions of normality which states that the sample size collected from a normally distributed population with 100 students should have a sample size of at-least 30 students.
- This condition approximates that the sample collected is also random and and follows a normal distribution like the population ( i.e total number of students = 100 ) itself.
- However, the spread of the data sigma = 3,000 is very large but it does not invalidates the condition of normally distributed sample, it only means that values are spread wide about the mean = 400.
Answer:

Step-by-step explanation:
Multiply 8 by 2, then add six and you get your answer.
Answer:
( -4 , 13 )
Step-by-step explanation:
2 ( -4 ) + ( 13 ) = 5
5 = 5
3 ( 13 ) = 15 - 6 ( -4 )
39 = 39
( -4 , 13 )
