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: $\mu-\sigma$ to $\mu+\sigma$

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

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

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: $21$ to $29$

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: $19$ to $31$

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.
