Question 3 Calculate the single-sided upper bounded 95% confidence interval for the population mean (mu) given that a sample of size n=5 yields a sample mean of 8.78 and a sample standard deviation of 0.54. Your answer: mu < 9.06 mu<8.82 mu < 9.74 mu < 9.79 mu < 9.22 mu < 9.29 mu < 9.11 mu < 9.69 mu < 9.22 mu < 8.92

In a 95% confidence interval. i 1-0.0s is called the confidence coefficient. A) True lB) False If a 95% confidence interval on the mean has a lower limit of 10 and an upper limit that 95% of the time the true value of the mean is between 10 and 15. ) True B) False For a fixed value of the standard deviation and a fixed sample size, a confidence inte population mean will get longer as the level of confidence...

Explain what "95% confidence" means in a 95% confidence interval. What does "95% confidence" mean in a 95% confidence interval? A. If 100 different confidence intervals are constructed, each based on a different sample of size n from the same population, then we expect 95 of the intervals to include the parameter and 5 to not include the parameter. B. The probability that the value of the parameter lies between the lower and upper bounds of the interval is 95%....

one can calculate the 95% confidence interval for the mean with the population standard deviation knowing this gives us an upper and lower confidence limit what happens if we decide to calculate the 99% confidence interval describe how the increase in the confidence level has changed the width of the confidence interval the same for the confidence interval set at 80% including example with actual numeric value for the intervals and you're supposed to help with your explanations
