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!!!

How do I make the equation in slope intercept form for No. 4?
dezoksy [38]

Since the slope and the y-intercept for the equation of y = mx + b doesn't exist, you don't need to include it.

y = mx + b

Without the m and b, which are the slope and y-intercept, you are left with x.

Then, you need to figure out whether the line is horizontal, or vertical.

If the line is vertical, you keep the x, and find out the value x is on for every point of y.

If the line is horizontal, you keep the y, and find out the value y is on for every point of x.

Since the line is vertical, we can use x = ?

The line is always at x=2, no matter what the y-value is, so the final equation would be x=2.

<em>I hope this helped you! :)</em>

A circle is defined by the equation given below.
Ierofanga [76]
The circle equation is in the format (x – h)2 + (y – k)2= r2, with the center being at the point (h, k) and the radius being "r".

x²+y²-8x-6y+2 =0 -----(a)
(x-4)² = x² - 8x + 16
(y-3)² = y² - 6y + 9

Equation (a) can be rewritten as:
(x-4)² + (y-3)² + 2 - 16 - 9 = 0
(x-4)² + (y-3)² = 23

The coordinates for the center of the circle is: ( 4,3)
The radius is √23=4.8
