Answer:
d. improve the likelihood that the two groups will be comparable with regard to known and unknown confounding factors.
Explanation:
<u>Epidemiology is the term that is used to define a study in which the study is done on a defined population for the health related issues, that is about answering the who, when and where related to this study.</u>
In this given question also the experiment focuses on developing two different groups to understand and conduct the study and analysis properly, based on the suspected factor and how they react to it.
Thus, it will lead to compare the groups in order to make the analysis efficient keeping constant factors.
In probabilistic sense random error are independent. Also, assumptions
for random error, epsilon are mean equal to 0, variance equal to sigma squared
and normal distribution. General form of probabilistic is
y=deterministic+random error where y is the variable of interest. We always
assume that the mean value of the random error equals 0. E(y) =mean of y, E(y)
=deterministic component.
Answer:
Kerry buys a new sweater to wear this winter.
Jasmine buys a new car.
Explanation:
Gross domestic product is the total sum of final goods and services produced in an economy within a given period which is usually a year
GDP calculated using the expenditure approach = Consumption spending by households + Investment spending by businesses + Government spending + Net export
Net export = exports – imports
Items not included in the calculation off GDP includes:
1. services not rendered to oneself
2. Activities not reported to the government
3. illegal activities
4. sale or purchase of used products
5. sale or purchase of intermediate products
The purchase of the sweater and the purchase of the new car constitutes consumption spending and it would be added as part of GDP.
The cash gift and Social Security check are transfer payment s and would not be included as part of GDP
Answer:
Which potential biological food safety hazard does smoking in food storage and prep areas cause?
Biological food safety hazards are enormous, food contamination on storage food materials can lead to food borne diseases as a result of contamination caused by micro-organisms ranges from bacteria, parasites among others.
Smoking could leave residue on food materials on storage, hence; increases the moisture content which enhances micro-organism growth and enables the food spoilage.
