Answer:
x = 14
Step-by-step explanation:
x- 9 = 5
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Add 9 to both sides of the equation: 
x - 9 (+9) = 5 (+9)
x = 5 + 9
x = 14
x = 14 is your answer.

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.
