A large number of randomized experiments were conducted to determine whether taking a particular drug regularly would decrease the chance of getting a certain disease. For each of the experiments, the drug effect is the difference between the proportion of people taking the drug who got the disease and the proportion of people taking a placebo who got the disease. If the drug had no effect whatsoever, which of the following experimental results would be anticipated?I. p-values will be greater than 0.05 for about 95 percent of the experiments.
II. There will be about an equal number of experiments showing positive and negative values of drug effect.
III. When 95 percent confidence intervals for the population drug effect are constructed, those confidence intervals include 0 about 95 percent of the time.
A) I only
B) II only
C) III only
D) I and II only
E) I, II, and III

E) I, II, and III

Explanation:

All these experiment results would be anticipated:

I. p-values will be greater than 0.05 for about 95 percent of the experiments.

II. There will be about an equal number of experiments showing positive and negative values of drug effect.

III. When 95 percent confidence intervals for the population drug effect are constructed, those confidence intervals include 0 about 95 percent of the time.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
