9. Which of the following is TRUE? ( 5 points) a. For a data set with mean = 25 pounds and Standard Deviation = 2 pounds then 95
pychu [463]

Answer:

For a data set with mean = 25 pounds and Standard Deviation = 3 pounds then 95% of the data is between 19 pounds and 31 pounds.

Step-by-step explanation:

1 ) 68% of the data lies within 1 standard deviation of mean  

This means 68% of data lies between:\mu-\sigmato \mu+\sigma

2) 95% of the data lies within 2 standard deviation of mean  

This means 95% of data lies between:\mu-2\sigmato \mu+2\sigma

3) 99.7% of the data lies within 3 standard deviation of mean

This means 99.7% of data lies between:\mu-3\sigma to\mu+3\sigma

Now,

95% of the data lies within 2 standard deviation of mean  :

For Mean = \mu = 25

Standard deviation = \sigma = 2

So,  95% of data lies between:25-2(2)to 25+2(2)

95% of data lies between:21to 29

For Mean = \mu = 25

Standard deviation = \sigma = 3

So,  95% of data lies between:25-2(3)to 25+2(3)

95% of data lies between:19to 31

So, Option D is true

For a data set with mean = 25 pounds and Standard Deviation = 3 pounds then 95% of the data is between 19 pounds and 31 pounds.

Determine whether the ffunction X/(x^2-1) is odd even or neither
djyliett [7]

equation is:

f(x) = \frac{x}{ {x}^{2} - 1 }

so if its even f(-x) should be equal to f(x)

that means

f( - x) =   \frac{ - x}{  {( - x)}^{2}  - 1}  \\  \\ f( - x) =     - \frac{ x}{ {x}^{2}  - 1}

so f(x) is not equal to f(-x) so its not even

If its odd than f(-x) should be equal to -f(x)

- f(x) =  - ( \frac{ x}{ { x}^{2} - 1 } ) \\  - f(x) =    - \frac{ x}{ {x}^{2} - 1 }

so as we can see f(-x)= - f(x)

so the function is odd

Ans:function is odd and not even
