A manufacturer plans to produce 100 reinforcing steel beams with tensile strength mean of 900 kips to be used in dam construction. Randomly, eight samples were selected and examined to measure the tensile strength to ensure that the design are in accordance with the specifications. The tensile strength of examined samples were: 825, 900, 915, 850, 870, 930, 835, and 885 kips. Determine the confidence interval for the mean of the tensile strength of the beams. [Use 10 % level of significance].

A paint manufacturer wants to determine the average drying time of a new interior wall paint. If for 12 test areas of equal size he obtained a mean drying time of 66.3 minutes and a standard deviation of 8.4 minutes, conduct a 95% confidence interval for the true mean .
In a random sample of 60 dog owners enrolled in obedience training, it was determined that the mean amount of money spen per owner was $109.33 per class. Assuming the sample standard deviation of the amount spent per owner is $12, construct and interpret a 95% confidence interval for the mean amount spent per owner for an obedience class.
A public health official in Okeechobee county needs to estimate the average systolic blood pressure of all residents in Okeechobee county for a report that is being prepared for the Florida Department of Health. The official randomly selected 66 Okeechobee county residents and found that the mean systolic blood pressure of the sample was 122 millimeters of mercury (mm Hg). Using a 96% confidence level, determine the margin of error, E, and a confidence interval for the mean systolic blood pressure of all Okeechobee county residents. From past research, it is known that the standard deviation of the distribution of all Okeechobee county residents' systolic blood pressure is 9 mm Hg. Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary. The margin of error is given by E= A 96% confidence interval is given by=
A public health official in Okeechobee county needs to estimate the average diastolic blood pressure of all residents in Okeechobee county for a report that is being prepared for the Florida Department of Health.The official randomly selected 128 Okeechobee county residents and found that the mean diastolic blood pressure of the sample was 74 millimeters of mercury (mm Hg).Using a 98% confidence level, determine the margin of error, EE, and a confidence interval for the mean diastolic blood pressure of all Okeechobee county residents. From past research, it is known that the standard deviation of the distribution of all Okeechobee county residents' diastolic blood pressure is 5 mm Hg.Report the confidence interval using interval notation. Round solutions to two decimal places, if necessary.The margin of error is given by E=A 98% confidence interval is given by

The quality-control manager of a chemical company randomly sampled twenty 100-pound bags of fertilizer to estimate the variance in the pounds of impurities. The sample variance was found to be 6.62. Find a 95% confidence interval for the population variance in the pounds of impurities.
In a sample of seven cars, each car was tested for nitrogen-oxide emissions (in grams per mile) and the following results were obtained: 0.06, 0.11, 0.16, 0.15, 0.14, 0.08, 0.15 (based on data from the Environmental Protection Agency). Assuming that this sample is representative of the cars in use, construct a 95% confidence interval estimate of the mean amount of nitrogen-oxide emission for all cars.
A public health official in Indian River county needs to estimate the average diastolic blood pressure of all residents in Indian River county for a report that is being prepared for the Florida Department of Health.The official randomly selected 137 Indian River county residents and found that the mean diastolic blood pressure of the sample was 79 millimeters of mercury (mm Hg).Using a 95% confidence level, determine the margin of error, EE, and a confidence interval for the mean diastolic blood pressure of all Indian River county residents.

As a follow-up to a report on gas consumption, a consumer group conducted a study of SUV owners to estimate the mean mileage for their vehicles. A simple random sample of 83 SUV owners was selected, and the owners were asked to report their highway mileage. The results that were summarized from the sample data were x=18.6 mpg and s=5.7 mpg. Based on these sample data, compute and interpret a 95% confidence interval estimate for the mean highway mileage for SUVs. The 95% confidence interval is ___mpg ------- ____mpg. (Round to one decimal place as needed. Use ascending order.) One can conclude_________
A civil engineer tested concrete samples to investigate the difference in strength, in newtons per square millimeter (N/mm2), between concrete hardened for 21 days and concrete hardened for 28 days. The engineer measured the strength from each sample, calculated the difference in the mean strength between the samples, and then constructed the 95 percent confidence interval, (2.9,3.1), for the difference in mean strengths. Assuming all conditions for inference were met, which of the following is a correct interpretation of the 95 percent confidence level? a) In repeated samples of the same size, approximately 95 percent of the samples will yield the interval 2.9 N/mm^2 to 3.1 N/mm^2. b) In repeated samples of the same size, approximately 95 percent of the sample means will fall between 2.9 N/mm^2 and 3.1 N/mm^2 c)In repeated samples of the same size, approximately 95 percent of the intervals constructed from the samples will extend from 2.9 N/mm^2 to 3.1 N/mm^2. d)In…
