This is a great place to start. When using ground beef to make hamburger patties, be sure to select the right meat. Lean ground beef like ground sirloin or the 7% fat meat will tend to make dry burgers.
Changes in lifestyles, nutrition, and ethnic composition of populations lead to changes in the distribution of body dimensions (e.g. the obesity epidemic), and require regular updating of anthropometric data collections.
The test statistic is called T. (This is not the same as the t test.) The statistic must be looked up in a table to find level of significance. The values of T range from 0 to 100. Unlike most tests, T must be less than or equal to the critical value to reject the null hypothesis.
