A 95% confidence interval for the mean (p) of a population is computed from a random sample and found to be 9 ± 3. Which of the following is a correct statement? O a. all of the above are true. O b. if we took many, many additional random samples and from each computed a 95% confidence interval for u, approximately 95% of these intervals would contain p. O c. 95% of values sampled are between 6 and 12. O d. there is a 95% probability that u is between 6 and 12. O e. there is a 95% probability that the true mean is 9 and a 95% chance that the true margin of error is 3.

You are trying to estimate the population mean p after taking a random sample from that population. Which of the following best represents a Margin of Error of about +/- 5% around the sample mean X? In other words, which best represents "95% confidence interval" around the observed mean, X? (In this notation, +/- stands for "plus or minus"; SD stands for "standard deviation"; and SE stands for "standard error.") p=X +- 2(SE) H= 2(SE) +/- X p =X+- 2(SD)

Use the following information for questions 3 and 4. A study of class lengths at two schools was done using independent samples. 31 classes were chosen from each. The first school had a mean length of 50.1 minutes and a standard deviation of 1.6 minutes. The second school had a mean length of 48.9 and a standard deviation of 2.2 minutes. We want to determine at α = 0.01 if the means are different. Assume all test conditions are satisfied. What are the null and alternate hypotheses (write in equation/inequality form)?
