Answer:
D) P-045 says that a response this small or smaller would be seen in sample data almost half the time when in fact there is no effect in the entire population of rats. That is, a response this size would often happen just by chance.
Step-by-step explanation:
The P-value represents the probability of getting the test sample results given that the null hypothesis is true.
A P-value that is low enough (smaller than the significance level) gives statistical evidence to support that the null hypothesis is not true.
In this case, a P-value of 0.45 does not represent a strong evidence against the null hypothesis, as there is 45% of chances of getting this sample results if the null hypothesis is true.
In this case, as we talk about differences ("no difference was seen" between the two groups), we know that the sample difference has not been large enough to be proved statistically significant.
So the right answer is Option d).

Answer:
4 and 6 are complementary because they are alternate exterior angles
Answer:
It would take 54 minutes.
Step-by-step explanation:
Since the miles are divided by 9 and it takes Molly 6 minutes to run 1/9 of a mile, you would multiply 6 by 9.
6x9 = 54
K + 77 = 2k - (16 - 89)
k + 77 = 2k - (-73)
k + 77 = 2k + (73)
k - 2k = 73 - 77
change the signs
k = 4
