The y intercept is where the line crosses the y axis. Hope that helped
There is no common multiple is there?
Answer:
B. the results are not statistically significant at level = 0.05, but they are practically significant.
Step-by-step explanation:
Given that the average Math SAT score for all students taking the exam this year is 480 with standard deviation 100.
Sample size n =4
mean difference = 550-480 = 70
Std error of sample =
Since sample size is small t test can be done with df =3
(one tailed test)
t =
p value =0.128
Since p >0.05 we accept null hypothesis.
B. the results are not statistically significant at level = 0.05, but they are practically significant.
