Calculate (step by step) the upper bound of a 95% confidencce interval for a sample of (N = 504) with a sample standard deviation of 2.26 and the sample mean of 2.96? Explain the step by step process in detail.
the lower bound = and upper bound = and upper bound! B eton Med Based on interviews with 95 SARS patients, researchers found that the meanincubation period was 56 days, with a standard deviation of 15.7 days. Based on this information, construct a 95% confidence Interval for the mean incubation period of the SARS Virus Interpret the interval The lower bound is days. (Round to two decimal places as needed.)
The upper bound is ___ A simple random sample of size n = 40 is drawn from a population. The sample mean is found to be x = 120.2 and the sample standard deviation is found to be s = 12.7. Construct a 99% confidence interval for the population mean. The lower bound is . (Round to two decimal places as needed.)
Given the data listed in the table, calculate the lower and upper bound for the 95% confidence interval for the mean at X = 6. The regression equation is given by y^ = b0 + b1x.

A. The lower and upper bound is? B. Interpret the interval. Based on interviews with 92 SARS patients, researchers found that the mean incubation period was 4.5 days, with a standard deviation of 14.2 days. Based on this information, construct a 95% confidence interval for the mean incubation period of the SARS virus. Interpret the interval. The lower bound is days. (Round to two decimal places as needed.)
calculate the 95% confidence interval using the appropriate formula for this sample size. Remember to add and subtract the margin of error from the sample mean to calculate the lower and upper bounds of the confidence interval.

Calculate the single-sided upper bounded 95% confidence interval for the population mean (mu) given that a sample of size n=12 yields a sample mean of 15.18 and a sample standard deviation of 3.89. Yanıtınız: O mu < 16.76 O mu < 17.67 O mu < 16.21 O mu < 17.20 mu < 16.03 mu < 17.36 mu< 18.92 O mu < 16.87 mu < 17.58 mu< 17.76
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)...
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
