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:

99% of confidence intervals for mean age of ICU patients

(53.8920 , 61.2079)

Step-by-step explanation:

Explanation:-

Given sample mean $x^{-} = 57.55$

Given standard error is determined by

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

Given data standard error = 1.42

99% of confidence intervals for mean is determined by

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

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

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

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

(53.8920 , 61.2079)

Conclusion:-

99% of confidence intervals for mean is determined by

(53.8920 , 61.2079)

$2 = \frac{m}{2} - 7$

$= 4 = m - 14$

$= m - 14 = 4$

$= m = 4 + 14$

$= m = 18$

Emerson purchased a game that was on sale for 18% off. The sales tax in his county is 8%. Let y represent the original price of

Juli2301 [7.4K]

Answer:

Step-by-step explanation:

Let us see...

y is the price.

Then, 18% off. This is:

y - (y*0.18) = 0.82*y

Then, we add 8%, so now it's 1.08% of this expression:
