In order to determine the average weight of carry-on luggage by passengers in airplanes, a sample of 60 pieces of carry-on luggage was collected and weighed. The average weight was 27.5 pounds. Assume that we know the standard deviation of the population to be 7.25 pounds. Also, assume the population is normally distributed. (Round your answers to three decimal places.) (a) Determine a 99% confidence interval estimate for the population mean weight (in pounds) of the carry-on luggage. pounds to pounds (b) Determine a 95% confidence interval estimate for the population mean weight (in pounds) of the carry-on luggage. pounds to pounds

A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with u = 520. The teacher obtains a random sample of 2200 students, puts them through the review class, and finds that the mean math score of the 2200 students is 525 with a standard deviation of 110. Complete parts (a) through (d) below. (a) State the null and alternative hypotheses. Let u be the mean score. Choose the correct answer below. O A. Ho: H= 520, H,: µ> 520 %3D B. Ho: μ 520 С. Но: и> 520, Hа: p#520 D. Ho: и%3D520, Hа: p#520 (b) Test the hypothesis at the a = 0.10 level of significance. Is a mean math score of 525 statistically significantly higher than 520? Conduct a hypothesis test using the P-value approach. Find the test statistic. to = %3D
The birth weight of newborn babes (measured by O'Cathain et al, 2002 n = 3226) is approximately normally distributed with a mean of 3.39kg and standard deviation of 0.55kg. Rounded to three decimals, What weight does a baby have to have to be in the 97%?
The weights of 1,000 men in a certain town follow a normal distribution with a mean of 150 pounds and a standard deviation of 15 pounds. From the data, we can conclude that the number of men weighing more than 165 pounds is about , and the number of men weighing less than 135 pounds is about .

#4data: 0.06, 0.11, 0.16, 0.15, 0.14, 0.08, 0.15. Use the sample data from #4 to construct a 98% confidence interval estimate for the standard deviation of the amount nitrogen-oxide emission for all cars.
The standard deviation, S, for the annual medical cost of 24 households was found to equal $1689 find a 95% confidence interval for the standard deviation of the annual medical cost for all households. Assume medical costs are normally distributed.
The heights of adult men in America are normally distributed, with a mean of 69.6 inches and a standa deviation of 2.61 inches. The heights of adult women in America are also normally distributed, but with mean of 64.7 inches and a standard deviation of 2.56 inches. If a man is 6 feet 3 inches tall, what is his Z-score (to two decimal places)?
The distribution of the student heights at a large college is approximately bell shaped. If the mean height is 66 inches,and approximately 95% of the heights fall between 32 and 100 inches, then, the standard deviation of the heightdistribution is approximately equal to
In a certain country the heights of adult men are normally distributed with a mean of 70.2 inches and a standard deviation of 2.7 inches. The country's military requires that men have heights between 66 inches and 79 inches. Determine what percentage of this country's men are eligible for the military based on height. The percentage of men that are eligible for the military based on height is nothing%. (Round to two decimal places as needed.)

I have a question: You are interested in estimating the the mean weight of the local adult population of female white-tailed deer (doe). From past data, you estimate that the standard deviation of all adult female white-tailed deer in this region to be 21 pounds. What sample size would you need to in order to estimate the mean weight of all female white-tailed deer, with a 94% confidence level, to within 4 pounds of the actual weight?
