Which of the following are true? If false, explain briefly. ​a. A very high​ P-value is strong evidence that the null hypothesis is false. ​
b. A very low​ P-value proves that the null hypothesis is false. ​
c. A high​ P-value shows that the null hypothesis is true.
d. A​ P-value below 0.05 is always considered sufficient evidence to reject a null hypothesis.

The correct options are;

a. False

b. True

c. True

d. False

Step-by-step explanation:

We look at each of the options as follows

a. A very high p-value is strong evidence that the null hypothesis is false;

The above statement is false because the p-value indicates the likelihood of the null hypothesis being correct, therefore, a high p-value is indicative of the correctness (truth) of the null hypothesis

b. A very low p-value shows that the null hypothesis is false

The above statement is true

c. A high p-value shows that the null hypothesis is true

The above statement is true

d. A P-value below 0.05 is always considered sufficient evidence to reject a null hypothesis.

The above statement is false as the p-value below which we reject the null hypothesis is dependent on the value of the significance level, α.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
