Zachary completes a hypothesis test and finds that he rejects the null hypothesis. Which statement gives a reason for rejecting

padilas [110]

Answer:

The z-statistic lies in the critical region

Step-by-step explanation:

When a hypothesis test is performed, the decision to reject or not reject the null hypothesis is made on basis of following observations:

If the z-statistic falls in the critical or rejection region, there is enough evidence to reject the Null Hypothesis
If the z-statistic falls outside the critical or rejection region, there is not enough evidence to reject the Null Hypothesis.

In the given statement Zachary rejects the Null Hypothesis, this means the z-statistic she calculated must have been inside the critical or rejection region. Hence the correct answer would be:

The z-statistic lies in the critical region

Write the symbols for the probability that of all the outfielders, a player is not a great hitter.

Mumz [18]

The symbolic representation of the conditional probability

$P(G'|O) = \frac{P(G'nO)}{P(O)}$

This is a conditional probability problem ; which can be expressed explicitly as ;

The probability of not being a great hitter Given that the player is an outfielder
Recall :

Probability of A given B is defined as ;

$P(A|B) = \frac{P(AnB)}{P(B)}$

Let :

Probability that a player is an outfielders = P(O)

Probability that a player is a Great hitter = P(G)

Probability that a player is not a great hitter = P(G')

Probability that a player is not a great hitter given that he is an outfielder = P(OnG')

Therefore, we have :

$P(G'|O) = \frac{P(G'nO)}{P(O)}$
