Question 1 0/1 pt 9 10 99 @ Details You measure 46 watermelons' weights, and find they have a mean weight of 66 ounces. Assume the sample weights' standard deviation is 14.2 ounces. Based on this, construct a 90% confidence interval for the true population mean watermelon weight. Give your answers as decimals, to two places ounces Hint: your answer should be in the form x + E instead of interval notation. Submit Question Question 2 0/1 pt O 10 99 @ Details Assume that a sample is used to estimate a population mean u. Find the margin of error E that corresponds to a sample of size 11 with a sample mean of a =72.3 and a sample standard deviation of s - 18.1 at a confidence level of 95%. Report E accurate to one decimal place because the sample statistics are presented with this accuracy. E = Answer should be obtained without any preliminary rounding. However, the critical value may be rounded to 3 decimal places. Submit Question Question 3 0/1 pt 9 10 99 @ Details The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 59.2 for a sample of size 693 and standard deviation 16.8. 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).
