Arrowroot starch is used as a thickener in many foods such as puddings and sauces. It can also be used in cookies and other baked goods. The starch has an extremely bland taste, which makes it suitable for neutral diets. It is believed that arrowroot helps to soothe upset stomachs/nausea. Arrowroot powder should be whisked into a cool liquid before adding to a sauce or other liquid based recipe, and it should be added towards the end. As overcooking can destroy the gelling properties of arrowroot.
The margin of error for a particular statistic of interest is usually defined as the radius (or half the width) of the confidence interval for that statistic. The term can also be used to mean sampling error in general.he margin of error is a statistic expressing the amount of random sampling error in a survey 's results. It asserts a likelihood (not a certainty) that the result from a sample is close to the number one would get if the whole population had been queried.
The Critical Value. The critical value for our margin of error formula is denoted by zÎ±/2. This is the point z* on the standard normal distribution table of z-scores for which an area of Î±/2 lies above z*. Alternately is is the point on the bell curve for which an area of 1 - Î± lies between -z* and z*.
