Answer:

The correct answer is a. the scores are spread out within the groups, which makes it more difficult to see differences between groups.

Explanation:

Within-group variability implies that each group has many different scores within itself. For example, Group 1 has both high and low scores, Group 2 also has high and low scores, and so on. This implies that the scores are spread out within groups, rather than clustered together within groups.

If the scores are spread out within groups, then it is more difficult to see differences between groups. This is because all the groups appear similar as there are hardly any distinguishing characteristics for each group. Therefore, the researcher needs more participants to define each group accurately. Hence, option a is the correct answer.

Answer:

To reach this sales value by producing more child tickets than adult tickets, it will be necessary to sell 90 child tickets and 60 adult tickets.

Explanation:

In order for the sale of 150 tickets to give a value equal to 102 dollars, and the child tickets were sold in greater quantity than the adult tickets, we would need to sell 90 child tickets and 60 adult tickets. This can be confirmed by calculating:

60 * 0.8 = 48 dollars.

48 + (90 * 0.6) = 102 dollars.

Which is part of the selection process for all federal judges?

Roman55 [17]

Answer:

b. Being confirmed by the Senate

Explanation:

Regarding the selection process for all federal judges, Article II of the U.S. Constitution states the following:

... and he (The President) shall nominate, and by and with the advice and consent of the Senate, shall appoint ambassadors, other public ministers and consuls, judges of the Supreme Court, and all other officers of the United States, whose appointments are not herein otherwise provided for, and which shall be established by law.

Therefore, in order for a person to become a federal judge, they first have to be appointed by the President (who has to take into account the Senate's advice), and then they have to be confirmed by the Senate. This selection process is a clear example of how the Checks and Balances system work in the U.S., in which each branch of the government has the power to oversee, check and limit the other branches.

adell [148]

Answer:

True

Explanation:

It is not realistic because experiments with people are very diverse and complex. All people are different and adjust in one way or another in their way of being and in the changes. Time may not change anything when a person is not intending to change their actions or thoughts. The analysis is complicated and with the possibility of not getting the expected results.
