This latest revision for pork comes again on the advice of the FSIS, which says cooking cuts of pork to 145Â° F with a three minute rest is as safe as cooking them to 160Â° F, the previously recommended temperature, with no rest time.With a single temperature for all whole cuts of meat and uniform 3 minute stand time, we believe it will be much easier for consumers to remember and result in safer food preparation,â said Under Secretary Elisabeth Hagen in the USDAâs news release.
From Wikipedia. Point estimation. In statistics, point estimation involves the use of sample data to calculate a single value (known as a statistic) which is to serve as a best guess for an unknown (fixed or random) population parameter. More formally, it is the application of a point estimator to the data.
For a population with unknown mean and unknown standard deviation, a confidence interval for the population mean, based on a simple random sample (SRS) of size n, is + t* , where t* is the upper (1-C)/2 critical value for the t distribution with n-1 degrees of freedom, t(n-1).f the measurements follow a normal distribution, then the sample mean will have the distribution N(,) . Since the sample size is 6, the standard deviation of the sample mean is equal to 1.2/sqrt(6) = 0.49.
