Answer:
Step-by-step explanation:
hello,
from the question, we were not given the P-value. If the test result were statistically significant, this means that P < 0.05 , thus we will reject the null hypothesis. if P < 0.05, then we are saying that the probability that the teaching method affected the students in their final exams is less that 5%. hence we reject the null hypothesis.
on the other hand if the test result is not statistically significant, this means that the P-value, P > 0.05, thus we will fail to reject the null hypothesis because the probability that the teaching method affected the students performance in their final exam is greater than 5%.
Answer:
Simplify the expression:
3x3+x2+3x+4
Step-by-step explanation:
Round down to 54.6 because it is 5 or less.
(7+3)x(4-2)=39
I hope that helps
