rosijanka [135]

Answer:

$9398.50

Step-by-step explanation:

Given

$\$1 = 106.40\ ALL$

Required

Equivalent of 1,000,000 ALL

We have:

$\$1 = 106.40\ ALL$

and

$\$x = 1000000\ ALL$

Cross Multiply

$x * 106.40 = 1 * 1000000$

$106.40x = 1000000$

Solve for x

$x = 1000000/106.4$

<em></em> $x = \$9398.50$ <em> -- Approximated</em>

A statistician uses Chebyshev's Theorem to estimate that at least 15 % of a population lies between the values 9 and 20. Use thi

rjkz [21]

Answer:

\mu = 14.5\\

\sigma = 5.071\\

k = 1.084

Step-by-step explanation:

given that a statistician uses Chebyshev's Theorem to estimate that at least 15 % of a population lies between the values 9 and 20.

i.e. his findings with respect to probability are

$P(9$

Recall Chebyshev's inequality that

$P(|X-\mu |\geq k\sigma )\leq {\frac {1}{k^{2}}}\\P(|X-\mu |\leq k\sigma )\geq 1-{\frac {1}{k^{2}}}\\$

Comparing with the Ii equation which is appropriate here we find that

$\mu =14.5$

Next what we find is

$k\sigma = 5.5\\1-\frac{1}{k^2} =0.15\\\frac{1}{k^2}=0.85\\k=1.084\\1.084 (\sigma) = 5.5\\\sigma = 5.071$

Thus from the given information we find that

$\mu = 14.5\\\sigma = 5.071\\k = 1.084$
