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.
You would get something like this. This is because with the first kid, they can get either Heads or Tails, two possibilities.
After this, the second kid can also cause either Heads or Tails but they are building on what the first kid had already done, so four possibilities.
Thsi keeps on multiplying on and on by 2 the more kids who flip a coin.
Number 1: 317350
number 2: 352222
number 3: 5000 and 50
number 4: 25742 (in between 2008 and 2009) and 863564 in general
all in order from first to last, you are welcome friend
