    Number - 3 is a real number and also a rational number.
    Whole numbers are: the numbers: 0, 1, 2, 3, ...
    Integers are like the whole numbers, but they also include negative numbers ( as - 3 ).
    So - 3 is an integer and not a whole number.

SVEN [57.7K]

Answer: <em>She earned $72 per day. </em>

<em>The computation that will give Samantha's daily pay is: $\frac{\$3960}{5\times 11}$ </em>

Step-by-step explanation:

Samantha did not work on weekends. That means, <u>she worked for 5 days in a week</u>.

Given that, she worked at the insurance company for 11 weeks. So, <u>the total number of her working days</u> $=(5\times 11)= 55$

She earned a total of $3,960.

b. Find a 99% confidence interval for mean age of ICU patients using the facts that, in the sample, the mean is 57.55 years and

rjkz [21]

Answer:

<em>99% of confidence intervals for mean age of ICU patients</em>

<em>(53.8920 , 61.2079)</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

<em>Given sample mean </em> $x^{-} = 57.55$ <em></em>

Given standard error is determined by

S.E = $\frac{S.D}{\sqrt{n} }$

<em>Given data standard error = 1.42</em>

<em>99% of confidence intervals for mean is determined by</em>

$(x^{-} - Z_{0.01} \frac{S.D}{\sqrt{n} } , x^{-} + Z_{0.01} \frac{S.D}{\sqrt{n} } )$

$Z_{\frac{\alpha }{2} } = Z_{\frac{0.01}{2} } = Z_{0.05} = 2.576$

$(x^{-} - 2.576 S.E , x^{-} + 2.576 S.E)$

$(57.55 - 2.576X 1.42 , 57.55+ 2.576 X1.42)$

(53.8920 , 61.2079)

<u><em>Conclusion</em></u>:-

<em>99% of confidence intervals for mean is determined by</em>

<em>(53.8920 , 61.2079)</em>
