Assume that a sample is used to estimate a population mean In. Find the 53% confidence interval for a sample of size 16 with a mean of 49.3 and a standard deviation of 13.9. Enter your answer as an open- interval (Le. , parentheses} accurate to one decimal place {because the sample statistics are reported accurate to one decimal place}. Answer should he obtained without any preliminary rounding. However, the critical value ma}:r be rounded to 3 decimal places. You must estimate the mean temperature [in degrees Fahrenheit] with the following sample temperatures: Find the 95% confidence interval. Enter your answer as an open-interval [i.e., parentheses} accurate to two decimal places [because the sample data are reported accurate to one decimal place). Answer should he obtained without any preliminary rounding. You must estimate the mean temperature (in degrees Fahrenheit) with the following sample temperatures: 36.7 35.5 46.8 35 65.6 50.1 58.4 25.2 24.4 Find the 99% confidence interval. Enter your answer as an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported accurate to one decimal place). 99% C.I. =The effectiveness of a bloodvpressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 61.? for a sample of size 53? and standard deviation 11.4. Estimate how much the dmg will lower a typical patient's systolic blood pressure [using a 90% confidence level). Enter your answer as a trivlinear inequality accurate to one decimal place [because the sample statistics are reported accurate to one decimal place). Answer should he obtained without any preliminary rounding. The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 70.6 for a sample of size 509 and standard deviation 17.4. Estimate how much the drug will lower a typical patient's systolic blood pressure [using a 90% confidence level). Enter your answer as a tri-Linear inequality accurate to one decimal place [because the sample statistics are reported accurate to one decimal place). Answer should be obtained without any preliminary rounding. You must estimate the mean temperature [in degrees Fahrenheit] with the following sample temperatures: l. .b. 15.?r Find the 95% confidence interval. Enter your answer as an open-inte nral [i.e., parentheses} accurate to two decimal places [because the sample data are reported accurate to one decimal place). Answer should he obtained without any preliminary rounding. Assume that a sample is used to estimate a population mean FL. Find the W% confidence interval for a sample of size 55 with a mean of 4?.5 and a standard deviation of 13.1 Enter your answer as an open- interval [i.e., parentheses} accurate to one decimal place {became the sample statistics are reported accurate to one decimal place}. Answer should he 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 proportion /4. Find the margin of error M.E. that corresponds to a sample of size 68 with a mean of 17.9 and a standard deviation of 8.9 at a confidence level of 99.5%. 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.F = Express the confidence interval (67.7, 147.1 ) in the form of ~ + ME
