The effectiveness of a blood-pressure drug is beinginvestigated. An experimenter finds that, on average, thereduction in systolic blood pressure is 60.9 for a sample ofsize 21 and standard deviation 16.9. Estimate how muchthe drug will lower a typical patient's systolic bloodpressure (using a 90% confidence level). Assume the data isfrom a normally distributed population.Enter your answer as a tri-linear inequality accurate tothree decimal places.

A question I have is the effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 27.7 for a sample of size 912 and a standard deviation of 21.3.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). < μ <
The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 32.3 for a sample of size 26 and standard deviation 15.7. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 98% confidence level). Assume the data is from a normally distributed population. Enter your answer as a tri-linear inequality accurate to three decimal places. Question Help: MMessage Instructor Submit Question 耳 Rain.. A E O G x メ 2 +66
Solve the following. Show your complete solution. The in-city gasoline mileage per gallon was computed for two economy automobiles, each for 40 tanks of gasoline. The mean and standard deviation of the mile per gallon readings were given in the following table. Find a 90% confidence interval for the difference in mean miles per gallon for the two automobiles. Interpret your result.
suppose that a category of world-class runners are known to run a marathon (26 miles) in an average of 143 minutes with a standard deviation of 14 minutes. consider 49 of the races. Let x̅ = the average of the 49 races. I need help finding the median of the average running times. if someone could explain how to solve this problem that would be great
A fitness company is building a 20-story high-rise. Architects building the high-rise know that women working for the company have weights that are normally distributed with a mean of 143 lb and a standard deviation of 29 lb, and men working for the company have weights that are normally distributed with a mean of 178 lb and a standard deviation or 32 lb. You need to design an elevator that will safely carry 18 people. Assuming a worst case scenario of 18 male passengers, find the maximum total allowable weight if we want a 0.995 probability that this maximum will not be exceeded when 18 males are randomly selected.maximum weight = -lb Round to the nearest pound.Answers obtained using exact z-scores or z-scores rounded to 2 decimal places are accepted The amounts of nicotine in a certain brand of cigarette are normally distributed with a mean of 0.956 g and a standard deviation of 0.302 g.

A certain statistics instructor participates in triathlons. The accompanying table lists times (in minutes and seconds) he recorded while riding a bicycle for five laps through each mile of a 3-mile loop. Use a 0.05 significance level to test the claim that it takes the same time to ride each of the miles. Does one of the miles appear to have a hill? Click the icon to view the data table of the riding times. Determine the null and alternative hypotheses. Ho: H₁: Find the F test statistic. F = Find the P-value using the F test statistic. P-value = What is the conclusion for this hypothesis test? (Round to four decimal places as needed.) (Round to four decimal places as needed.) C O A. Fail to reject Ho.

A researcher is interested in whether participating in sports positively influences self-esteem in young girls. She identifies a group of girls who have not played sports before but are now planning to begin participating in organized sports. The researcher gives them a 50-item self-esteem inventory before they begin playing sports and administers the same test again after 6 months of playing sports. The self-esteem inventory is measured on an interval scale, with higher numbers indicating higher self-esteem. In addition, scores on the inventory are normally distributed. The scores are as follows: Before 44 40 39 46 42 43 After 46 41 41 47 43 45 What statistical test should be used to analyze the data Check the claim. If significant ,compute and interpret the effect size
