Answer:
D.
7.68 × 108
Step-by-step explanation:
World population in 2013 was about 7.125 billion
In 2003 , it was about 6.357 billion
Increase = 2013 population- 2003 population
That’s 7.125 billion - 6.357 billion = 0.768 billion
A billion has 9 zeros. When you move The point one place to the right , it reduces the number of zeros by one. you now have
7.68 x 10^8
14/16 or anything like that
Answer:
The P-value is 0.0166.
Step-by-step explanation:
<u>The complete question is:</u> In a one-tail hypothesis test where you reject H0 only in the lower tail, what is the p-value if ZSTAT = -2.13.
We are given that the z-statistics value is -2.13 and we have to find the p-value.
Now, the p-value of the test statistics is given by the following condition;
P-value = P(Z < -2.13) = 1 - P(Z
2.13)
= 1 - 0.9834 = <u>0.0166</u>
Assuming that the level of significance is 0.10 or 10%.
The decision rule for rejecting the null hypothesis based on p-value is given by;
- If the P-value of the test statistics is less than the level of significance, then we have sufficient evidence to reject the null hypothesis.
- If the P-value of the test statistics is more than the level of significance, then we have insufficient evidence to reject the null hypothesis.
Here, the P-value is more than the level of significance as 0.0166 > 0.10, so we have insufficient evidence to reject the null hypothesis, so we fail to reject the null hypothesis.
That would be the commutative property
