Government data show that 9% of the American population are at least 75 years of age. To test a random-digit dialing device, you

Lubov Fominskaja [6]

Answer: 9% parameter, 3% statistic

Step-by-step explanation: Parameter and statistic are are statistical terms used to describe a group or observation.

However, the distinction between a parameter and a statistic is in the measured observation.

Parameter is used to describe an entire population while statistic is used to describe a sample.

Where a population refers to the entire number of people or inhabitant of a particular country while a sample refers to a subset of observation drawn randomly from a population which serves a representative of the entire population.

In the question above, 9% is used to make a description of the whole American population who are at least 75 years of age. While,

3% is used to describe a subset of the American population (sample) who are 75 years or older.

Represent the number 108 in expanded form and exponent

lubasha [3.4K]

<h3>Further explanation</h3>

Let's recall following formula about Exponents and Surds:

$\boxed { \sqrt { x } = x ^ { \frac{1}{2} } }$

$\boxed { (a ^ b) ^ c = a ^ { b . c } }$

$\boxed {a ^ b \div a ^ c = a ^ { b - c } }$

$\boxed {\log a + \log b = \log (a \times b) }$

$\boxed {\log a - \log b = \log (a \div b) }$

<em>Let us tackle the problem!</em>

$\texttt{ }$

$108 = 54 \times 2$

$108 = (27 \times 2) \times 2$

$108 = (9 \times 3) \times 2 \times 2$

$108 = (3 \times 3) \times 3 \times 2 \times 2$

$108 = 3^3 \times 2^2$

$\texttt{ }$

<h3>Conclusion:</h3>

The number 108 could be represented in expanded form and exponent as following:

$\boxed{ 108 = 3^3 \times 2^2 }$

$\texttt{ }$

For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard dev

topjm [15]

Answer:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$

Step-by-step explanation:

For this case we have the following parameters given:

$\mu = 9.2 , \sigma =1.6$

We select a ample size of n=49. And we want to find this probability:

$P(\bar X> 9.3)$

And for this case is a right tail probability and we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$
