A statistical procedure to estimate the mean shell thickness of eggs from chickens contaminated with PCBs obtains a point estimate of 0.70 mm and an estimated error margin of 0.05 mm. This means:
|
The standard deviation of actual shell thickness in the sample was 0.05 mm. |
||
|
We are 95% confident that the sample mean shell thickness is 0.70mm with a margin of 0.05mm. |
||
|
An estimate of the standard deviation of the sample mean shell thickness over repeated samples is 0.05 mm |
||
|
The standard deviation of the population mean over all eggs is about 0.05 mm. |
||
|
A 95% confidence interval for the sample mean shell thickness is 0.70mm ± 5mm |

Selecting a random sample is an example of a statistical experiment, and the sample statistic p is a numerical description of the result of the experiment. Therefore, p is a random variable. The probability distribution of p is called the sampling distribution of p In practice, you select one random sample and use the information from that sample to estimate the population parameter of interest. However statisticians sometimes perform a procedure called repeated sampling, in which the experiment is run...

1. The sampling distribution of the sample mean Structural steel is often treated with a protective coating (called an intumescent coating) that insulates the steel against damage from fire. Coatings are rated according to the number of hours of high-temperature exposure the treated steel can withstand, but if the coating is not applied with a mean thickness within the range specified by its manufacturer, the protection it provides will last for a shorter time than its rating. An office tower under construction...

8. value: 10.00 points An experiment was conducted to determine the effectiveness of a method designed to remove oil wastes found in soil. Three contaminated soil samples were treated. After 95 days, the percentage of contamination removed from each soil sample was measured, with a mean of 49.3 percent and a standard deviation of 1.5 percent. If we wished to narrow the boundary around u for a 98 percent confidence interval to within 0.5 percent, how many soil samples should...
