Assume that a sample is used to estimate a population proportion p. Find the 99% confidence interval for a sample of size 144 with 34% successes. Enter your answer as an open-interval (i.e., parentheses) using decimals (not percents) accurate to three decimal places. 99% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 15. Find the critical value that corresponds to a confidence level of 98%. (Report answer accurate to three decimal places with appropriate rounding.) ta/2 = ± _________

You intend to estimate a population mean with a confidence interval. You believe the population to have a normal distribution. Your sample size is 53. Find the critical value that corresponds to a confidence level of 99.5%. (Report answer accurate to three decimal places with appropriate rounding.) ta/2 = ±

Assume that a sample is used to estimate a population mean μμ. Find the 99.5% confidence interval for a sample of size 59 with a mean of 62.5 and a standard deviation of 12.2. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.5% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that a sample is used to estimate a population mean μμ. Find the 99.9% confidence interval for a sample of size 62 with a mean of 19.4 and a standard deviation of 12.3. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place). 99.9% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that a sample is used to estimate a population mean μ. Find the 90% confidence interval for a sample of size 35 with a mean of 55.8 and a standard deviation of 5.7. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place. An example of such an answer is "(66.9,82.4)". 90% C.I. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.

Assume that a sample is used to estimate a population mean u. Find the margin of error M.E. that corresponds to a sample of size 6 with a mean of 20.1 and a standard deviation of 14.5 at a confidence level of 99%. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. M.E. = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places.
