Sample Mean

Explanation:

The sample mean is defined as the average of a certain number of observations from the sample. The sample mean from a group of observations is an estimate of the population mean.

The mean of a sample is actually the sum of all the sample measurements. If the experiment is random, then the mean sample can be used to estimate the general population.

The veterinary research had a sample of 60 horses in total and observed the average age of the horses with colic is 12 years. The 12years represents the sample mean as it can also be used to estimate the population mean.

Sample mean

Explanation: The value 12 is given as the sample mean. "A veterinary researcher takes an SRS of 60 horses presenting with colic" defines the sample; "The average age of the 60 horses with colic is 12 years." gives the sample average or sample mean.

A sample mean is defined as the average of the statistical samples collected. A sample mean will not equal the population mean (the average of all the values in the population), however, if the sample is a simple random sample, the sample mean gives an unbiased estimate of the population mean.

Currently, as of february 2016, an american traveling in france would be by the exchange rate. the weakness of the euro and the strength of the us dollar means that items in france cost less to an american than they otherwise would. of course, if this trend reverses and the us dollar weakens and the euro strengthens, such as was happening in early 2008, an american traveling in france would have an adverse experience because items would cost relatively more.
