Confidence Interval Given. Assume I created a 95% confidence interval for the mean hours studied for a test based on a random sample of 64 students. The lower bound of this interval was 4 and the upper bound was 14. Assume that when I created this interval I knew the population standard deviation. Using this information, (a) Calculate the width of the interval. (b) Calculate the margin of error for the interval. (c) Calculate the center of the interval. (d)...

The 95% lower confidence bound for a population parameter θ is 9.232. The point estimate from the sample used to construct this bound is 15.7. Use this information to compute the standard error in the sample in both of the following cases. a) If this is a two-sided confidence interval, then the standard error is: b) If this is a one-sided confidence interval, then the standard error is:
