2) (10 points) Answer each of the following True False questions. . (True or false?) When we create confidence intervals, the interval is always an estimate of the statistic, not the parameter (True or false?) When we create confidence intervals, the value in the center of the interval is always the observed statistic from our sample. (True or false?) Holding all other things constant, a 99% confidence interval will always be wider than a 95% confidence interval. True or false 7) If we are testing vs., and we reject the null hypothesis, then that tells us that 72 will be in the associated confidence interval estimate of the population parameter. (True or false) As sample size gets bigger, the margin of error in a confidence interval gets bigger 3) (8 points) Confidence interval components. Re-write the confidence interval using interval notation in order to give the lowest value and the highest value in the confidence interval. Suppose a confidence interval is.
