A researcher wants to estimate the mean commute time of residents in Westchester County. The researcher samples 40 commuters and
Ksenya-84 [330]

Answer:

21.759

Step-by-step explanation:

Given that :

Mean (m) = 25

Standard deviation (s) = 12.5

Sample size (n) = 40

α = 90%

The confidence interval is obtained using the relation:

Mean ± Zcritical * s/sqrt(n)

Zcritical at 90% confidence interval = 1.64

25 ± 1.64 * (12.5/sqrt(40))

Lower boundary : 25 - 1.64(1.9764235) = 21.75866546

Upper boundary : 25 + 1.64(1.9764235) = 28.24133454

(21.759, 28.241)

Hence, lower bound of confidence interval is : 21.759

Help!!!How does the slope of g(x) compare to the slope of f(x)?
attashe74 [19]

we know that

The formula to calculate the slope m between two points is equal to

m=\frac{(y2-y1)}{(x2-x1)}

Step 1

<u>Find the slope of the function f(x)</u>

Let

A( 0,-2)\\B(1,0)

substitute the values in the formula  above

m=\frac{(0+2)}{(1-0)}

m=2

<u>the slope of the function f(x) is m=2</u>

Step 2

<u>Find the slope of the function g(x)</u>

Let

C( -4,0)\\D(0,2)

substitute the values in the formula  above

m=\frac{(2-0)}{(0+4)}

m=\frac{2}{4}

m=\frac{1}{2}

the slope of the function g(x) is m=\frac{1}{2}

therefore

slope f(x) > slope g(x)

or

slope g(x) < slope f(x)

<u>the answer is the option </u>

B.The slope of g(x) is less than the slope of f(x).

A simple random sample of 64 observations was taken from a large population. The population standard deviation is 120. The sampl

Answer:

<h3>The standard error of the mean is <u>15</u></h3>

Step-by-step explanation:

Given that a simple random sample of 64 observations was taken from a large population.

Hence it can be written as n=64

The population standard deviation is 120.

It can be written as \sigma_{\overline{X}}=120

The sample mean was determined to be 320.

It can be written as \overline{X}=\mu =320

<h3>To find the standard error of the mean :</h3>

The formula for the standard error of the mean is given by

\sigma_{\overline{X}}=\frac{\sigma}{\sqrt{n}}

Now substitute the values in the formula we get

\sigma_{\overline{X}}=\frac{120}{\sqrt{64}}

=\frac{120}{8}

=15

\sigma_{\overline{X}}=15

<h3>∴ The standard error of the mean is 15</h3>
