Business statistics is a scientific approach to decision-making in the face of risk and is
used in many disciplines, such as financial analysis, econometrics, auditing, production
and operations, and marketing research. The main objective of business statistics is to
make inferences about certain characteristics of a population based on information
contained in a random sample from the entire population.
,Statistical forecasting concentrates on using the past to predict the future by identifying
trends, patterns and business drives within the data to develop a forecast. This forecast is
referred to as a statistical forecast because it uses mathematical formulas to identify the
patterns and trends while testing the results for mathematical reasonableness and
confidence. Statistical forecasting is used for forecasting sales and budget.

answer is: True
How to solve this question?
The passage says that statistical forecasting concentrates on using the past to identify
patterns and trends. This information is used to predict the future, such as forecasting
sales and budget. Therefore, the answer is "True".

Soy- and rice- based diets are very popular in Third World countries. The soy bean has a
higher phytate content than any other grain or legume that has been studied. Phytate is an
organic acid, present in the bran or hulls of all seeds, which blocks the uptake of essential
minerals - calcium, magnesium, iron and especially zinc - in the intestinal tract.
Soy beans seem to be highly resistant to many phytate-reducing techniques such as long,
slow cooking. Only a long period of fermentation will significantly reduce the phytate
content of soy beans. Thus, fermented products such as tempeh and miso provide
nourishment that is easily assimilated. When precipitated soy products are consumed with
meat, the mineral-blocking effects of the phytates are reduced.
Question #4
People in Third World countries have low levels of calcium, magnesium, iron and zinc
