Answer:

see explanation

Step-by-step explanation:

Given

\frac{\frac{1}{x} }{(\frac{1}{x})^2+1 }

= \frac{\frac{1}{x} }{\frac{1}{x^2}+1 }

Multiply numerator/ denominator by x² to clear the fractions

= \frac{\frac{1}{x}(x^2) }{(\frac{1}{x^2}+1)x^2 }

= \frac{x}{1+x^2}

= \frac{x}{x^2+1}

A tax assessor wants to assess the mean property tax bill for all homeowners in a certain state. From a survey ten years ago, a
Jet001 [13]

Answer:

The answer is below

Step-by-step explanation:

From the table, the mean (μ) = 1390.75 and the standard deviation (σ) = 518.75

The confidence level (C) = 90% = 0.9

α = 1 - C = 1 - 0.9 = 0.1

α/2 = 0.1 / 2 = 0.05

The z score of α/2 (0.05) is the same as the z score of 0.45 (0.5 - 0.05) which is equal to 1.645.

The margin of error (E) is given as:

E=Z_\frac{\alpha}{2}*\frac{\sigma}{\sqrt{n} }  \\\\E=1.645*\frac{518.75}{\sqrt{14} } =228.07

The confidence interval = μ ± E = 1390.75 ± 228.07 = (1162.68, 1618.82)

The confidence interval is between 1162.68 and 1618.82.
