Answer:
YES ALL THE CONDITIONS HAVE BEEN MET
Step-by-step explanation:
H o:mu1=mu2
Ha:mu1 not = mu2
n1=30
n2=30
large samples follows normal distribution
and they are independent samples
we can conduct t test for 2 groups we can ignore that condition randomness
YES ALL THE CONDITIONS HAVE BEEN MET

Answer:
Dependent.
Quantitative.
Step-by-step explanation:
<u>Determine whether the sampling is dependent or independent.</u>
This is a matched-pair data test, as the same students are measured two times in order to compare the results.
This type of samples are dependent, as they are correlated between them.
<u>Indicate whether the response variable is qualitative or quantitative.</u>
The response variable is the test score. This is a quantitative variable, as this can be defined by a number. Both sample scores are averaged and compared.
Answer = V (2,1)
Because:
The equation of the circle is
(x+1)² + (y+3)² = 25
(2+1)² + (1+3)² = 25
3² + 4² = 25
9 + 16 = 25
25 = 25
