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

Tema [17]

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!!!

you just find the surface area for each rectangle/square and then add them together

5x8=40

25x5=125

8x25=200

5x25=125

8x25=200

add those numbers and you get 730 :)

True or False?In Exercise,determine whether the statement is true or false given that f(x) = In x.if it is false,explain why or

EastWind [94]

Answer:

False

Step-by-step explanation:

This is false. We can disprove this by plugging in the number into the function f(x) = lnx

f(0) = ln0

Since $e^{- \infty} = 0$ , $ln0 = -\infty$

This is not 0 so f(0) cannot be equal to 0, thus disproving the statement.

Edgar Anderson earns $300 per week plus 15% commission on all sales over 1,000. if Mr. Anderson's sales for one week are 2,500 w

vredina [299]

Since he only makes commission on sales over $1000, he makes commission on $1500 (we find this by doing 2500-1000.) His commission is 15%, so find 15% of $1500:
$.15*1500=225$
So we know how makes $225 in commission.

Now we need to add this to his fixed pay to get his total pay:
$225+300=525$
So his total pay is $525, which is answer 'a'

Hope I helped, and let me know if you have any questions :)
