You’ll need to divide 1,644 and 13 since the manager wants to put 1,644 polished rocks into small bags. And 13 rocks is how much will be in each bag. So you’ll do 1,644/ 15 = 109 with 6 left over. Hope it’s correct :)

Use the given degree of confidence and sample data to construct a confidence interval for the population mean mu.Assume that the

worty [1.4K]

Answer:

95% confidence interval for the true mean cholesterol content of all such eggs.

(173.8175 , 196.1825)

Step-by-step explanation:

Step(i):-

Given mean of the sample x⁻ = 185 milligrams

Given standard deviation of the sample 'S' = 17.6 milligrams

Level of significance

∝ = 0.05

$t_({\frac{\alpha }{2} , n-1 }) = t_{0.025 ,11} = 2.2010$

Step(ii):-

95% confidence interval for the true mean cholesterol content of all such eggs.

$(x^{-} - t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} } , x^{-} + t_{\frac{\alpha }{2} } \frac{S}{\sqrt{n} })$

$(185 - 2.2010 \frac{17.6}{\sqrt{12} } , 185 + 2.2010 \frac{17.6}{\sqrt{12} })$

( 185 - 11.1825 , 185 + 11.1825)

(173.8175 , 196.1825)

Final answer:-

95% confidence interval for the true mean cholesterol content of all such eggs.

(173.8175 , 196.1825)

the perimeter of a pool table is 30 ft.The table is twice as long as it is wide.what is the length of the pool table.

noname [10]

Perimeter is legnth +legnth + width + width or
P=2L+2W

L=2W
subsitute L=2W for L in P=2L+2W

P=2(2W)+2W
P=4W+2W
P=6W

we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width

subsitute W=5 for W in L=2W
L=2(5)
L=10

to check
10=2(10)+2(5)
30=20+10
30=30
checks

Legnght=10
Width=5
