Obesity: The National Center for Health Statistics conducted the National Health Interview Survey (NHIS) for 27,787 U.S. civilia

n noninstitutionalized adults in January – September 2014. According to an early release report, an estimated 29.9% of U.S. adults aged 20 and over were obese. Obesity is defined as a body mass index (BMI) of 30 kg/m 2 or more. True or false? The 29.9% is a parameter representing a population of 27,787 adults.

Answer:

The correct answer is 'False'

Step-by-step explanation:

In statistical analysis, the parameter represents a characteristic (usually numerical) that describes the entire population.

The parameter gives a clear picture of that characteristic (usually numerically) for the entire population, after sampling the entire population.

The sample equivalent of a parameter is called a statistic. A statistic describes that same characteristic (usually numerically), for a sample taken from the population.

The number of people that participated in this survey (27,787), although large, isn't the entire population of adults aged 20 and above in the U.S.

So, the 29.9% proportion of the sample surveyed that were found to be obese is at best a good estimation of the population proportion (due to the very large sample size).

It is however not correct, to say that the 29.9% is a parameter representing a population of 27,787 adults.

So, the 29.9% is more appropriately a statistic for the 27,787 adults sample.

Hope this Helps!!!

y

=

14

It is in the form

a

If a linear equation is in this form, then -

It slope is

−

a

b

In our case, we shall use this formula

m

-1/3x+2x=3 3/4 what does the variable represent?
svet-max [94.6K]
Start off by combining like terms on the LHS (the terms with x in them).

So we get \frac{-1}{3}x+2x= \frac{-1}{3}x+ \frac{6}{3}x= \frac{-5}{3}x

Replacing this result with what we had before on the LHS, we get \frac{-5}{3}x=3 \frac{3}{4}= \frac{9}{4}

⇒Solve for x (divide both sides \frac{-5}{3})
⇒Don't forget about reciprocity rules when dividing.  This is the same as multiplying both sides by \frac{3}{-5}

⇒x= \frac{9}{4}( \frac{3}{-5})&#10;
⇒x= -\frac{27}{20}=-1\frac{7}{20} ***This is a proper fraction
