1. Find the margin of error for the give values of c,s,and n C=0.90, s=3.3, n=100 Round to 3 decimal places as needed 2. Construct the confidence interval for the population mean C=0.90, x=5.1, s=0.3, and n=40 A 90% confidence for u is (_,_) round to 2 decimal places as needed 3. Construct the confidence interval for the population mean C=0.95, x=16.1, s=6.0, n=60 A 95% confidence interval for u is (_,_) round to one decimal place as needed 4. Use the confidence interval to find the estimated margin of error then find the sample mean. A biologist reports a confidence interval of 4.5,5.3 when estimating the mean height in centimeters of a sample of seedlings. 5. Find the minimum sample size n needed to estimate u for the given values of c, s, and E C=0.98, s=8.2, and E=1 Assume that a preliminary sample has at least 30 members. Round up to nearest whole number 6. Use the given confidence interval to find the margin of error and the sample proportion 0.603,0.633 7. People were polled on how many books they read the previous year. How many subjects are needed to estimate the number of books read the previous year within one book with 95% confidence? Initial survey results indicate that o=14.6 books. A 95% confidence level requires_subjects. Round up to the nearest whole number
