Answer:
A. Reject the null hypothesis because p-value < 0.005 is less than the significance level a = 0.05
Step-by-step explanation:
In hypothesis test, test statistic calculated and it's p-value is compared against the significance level. If it is less than the significance level, the result is significant at the given significance level. In this case one can reject the null hypothesis in favor of the alternate hypothesis.
In this example Katherine find test statistic -3.39, and p-value < 0.005. Thus she can conclude there is significant evidence that the population mean peak power is less than the advertised amount
Here is how to work 2, 3 , and 4.
Answer:
Enlargement
Step-by-step explanation:
The area is bigger
There won't be any change in the total mass of the atoms involved in a chemical reaction. According to the law of conservation of mass; it states that mass can neither be created nor destroyed in a chemical reaction. So, when atoms participate in a chemical reaction they might displace with other reactants but the total mass will remain the same.

For this case we have by definition, that the derivative of the position with respect to time is the velocity, that is to say:
So:
Taking into account that the derivative of a constant is 0.
So, the velocity is -14
Answer:
-14
