Answer: D) Increase the sample size and decrease the confidence level.
Step-by-step explanation:
A reduced interval width means that the data is more accurate. This can only be achieved if the sample size is increased because a larger sample size is able to capture more of the characteristics of the variables being tested.
A smaller confidence interval will also lead to a reduced interval width because it means that the chances of the prediction being correct have increased.
A. 18+2 = 20 abs 18-2= 17
Answer:
3x=18
Step-by-step explanation:
We want to get the variable x by itself.
Since we see a -3 with the 3x, we want to move the 3 to the other side of the equal sign by adding 3 to both sides of the equal sign.
3x - 3 = 15
3x - 3 + 3 = 15 + 3
Then we get:
3x + 0 = 18
3x = 18
