Answer:
labor force participation rate = 61.28 %
Explanation:
given data
adult population = 250 million
unemployment = 10.4 million
employment = 142.8 million
marginally attached workers = .8 million
to find out
labor force participation rate
solution
we know that labor force participation rate is equal to 100 × labor force (no of people employed + no of people unemployed) and divided by the adult non institutionalized population
so here
labor force participation rate = 100 × 
labor force participation rate = 61.28 %
The placebo effect is when somebody's physical or mental health appears to improve after accepting a placebo or 'dummy' treatment.
<h3>How does the placebo effect result in the brain?</h3>
The placebo effect increases activity in an area called the rostral ventromedial medulla, which transfers pain information, and reduces activity in the periaqueductal gray, which helps the body suppress pain. The nocebo effect generated the opposite change.
In anticipation of benefit when a placebo is administered, dopamine receptors are started in regions of the brain associated with prize. As further evidence that the placebo effect is a authentic biological phenomenon, genetics can influence the strength of the effect.

The correct answer is: TRUE.
<u>In order to measure qualitative data quantitively, categorical variables are used</u>. These type of variables are defined by a set of positive numbers, and each number is connected to a nominal category, which has been defined based on a qualitative property.
For example, if conducting a research about holiday patterns, one of the variables registered aims to measure the season in which people travel the most hence the following categories are defined: spring (=1), summer (=2), autumn (=3) and winter (=4). This is a categorical variable. If it only had two categories it is denominated a dummy or binary variable (values: 0, 1).
