They are used to make mushy peas, and also the snack food wasabi peas. Marrowfat peas with a good green color are exported from England to the Middle East and Japan for the snack food market, while paler peas are used for canning. Those with thin skins and a soft texture are ideal for making mushy peas. Marrowfat is a traditional, starchy, large-seeded variety of pea ("Pisum sativum" var.
Type I and type II errors II error is denoted by β. These error rates are traded off against each other: for any given sample set, the effort to reduce one type of error generally results in increasing the other type of error. For a given test, the only way to reduce both error rates is to increase the sample size, and this may not be feasible. A test statistic is robust if the Type I error rate is controlled. How likely the results are to be found if the null hypothesis is true is called statistical significance. These terms are also used in a more
