Answer:
C. becomes narrower
Step-by-step explanation:
If the confidence level is reduced from 95% to 90%, then, the confidence interval for u becomes narrower, i.e., we are less sure that the true value of u is contained inside the new interval. With a 95% confidence interval there is a probability of 0.95 that the parameter u is inside the interval and with a 90% confidence interval there is a probability of 0.90 that the parameter u is inside the interval.
Say you have 7 divided by 3.5
7/3.5 If you set up like this 3.5 into 7, you move the decimal over once in 3.5
So you now have 35 into 7. Next you have to move the decimal on the seven however many times you moved the first decimal. So 7 is now 70
Next you just do simple division 35 into 70 =2
