Question 11 2 Points Suppose That You Are Attempting To Determine The Necessary Sample Size Required To Compute An Int 1 (55.25 KiB) Viewed 20 times

Question 11 (2 points) Suppose that you are attempting to determine the necessary sample size required to compute an interval estimate with a margin of error no larger than 23.0. Further suppose that the population standard deviation is known to be 55.0 and the desired confidence level is 95%. Use the table on Ch 08 slide 13 for more precise values of z. Round your answer to two (2) decimal places (don't round up to the next largest integer, D2L doesn't have a round-up function so just report the value from the formula). Your Answer: Answer Question 12 (2 points) If a sample of size 11 has a mean of 391.1 with standard deviation of 8.4, how many degrees of freedom (df) does the sample have? Your Answer: Answer
