Find the margin of error M.E. that corresponds investigated. An experimenter finds that, on average, Fahrenheit) with the following sample temperatures: measure 37 watermelons' weights, and find they have a the reduction in systolic blood pressure is 60.8 for a 20.4 to a sample of size 8 with a mean of 77.4 and a sample of size 319 and standard deviation 7.5. -4.2 mean weight of 54 ounces. Assume the population standard deviation of 5.6 at a confidence level of -9.3 standard deviation is 14.8 ounces. Based on this, 99.9%. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 90% 9.8 construct a 90% confidence interval for the true confidence level). 40 population mean watermelon weight. Report ME accurate to one decimal place because the sample statistics are presented with this accuracy. Enter your answer as a tri-linear inequality accurate to Give your answers as decimals, to two places one decimal place (because the sample statistics are M. E. = Find the 90% confidence interval. Enter your answer as reported accurate to one decimal place). an open-interval (i.e., parentheses) accurate to two decimal places (because the sample data are reported H Answer should be obtained without any preliminary accurate to one decimal place) ounces rounding. However, the critical value may be rounded to 3 decimal places. 90% C.I. = Answer should be obtained without any preliminary Question 6 rounding. v Question 5 Answer should be obtained without any preliminary ounding. 0/2 pts 9 3 99 0 Details . Question 9 0/2 pts 9 3 99 0 Details 1> 0/2 pts 9 3 99 0 Details 0/2 pts 9 3 99 0 Details You measure 36 textbooks' weights, and find they have In a survey, 28 people were asked how much they spent SAT scores are distributed with a mean of 1,500 and a a mean weight of 43 ounces. Assume the population on their child's last birthday gift. The results were standard deviation of 300. You are interested in standard deviation is 11.5 ounces. Based on this roughly bell-shaped with a mean of $41 and standard A student was asked to find a 98% confidence interval estimating the average SAT score of first year students construct a 95% confidence interval for the true deviation of $13. Construct a confidence interval at a for widget width using data from a random sample of at your college. If you would like to limit the margin of population mean textbook weight . 90% confidence level. size n = 22. Which of the following is a correct interpretation of the interval 13.9
