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.
Answer:
Hello there! There is a 1/4 chance of getting the same result on both flips, keeping in mind that a coin only has 2 sides.
Step-by-step explanation:
There is a 1/2 chance of getting a result on one flip. So we now have to multiply that by getting the same result on another flip.
1/2 × 1/2 = 1/4
Hope this helps! :)
