Answer:

Median

Step-by-step explanation:

Center of distribution is the middle of a distribution, much like the median. The median of a set of numbers is the number in the middle. Since these two are pretty similar, median would be the best to describe the centers of distribution out of the terms provided.

Edit: I'm leaning towards B.) Both aren't symmetrical

Naya [18.7K]

Answer:

Test statistic |Z| = 0.1040 < 1.96 at 0.05 level of significance

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that a report on the nightly news broadcast stated that 10 out of 108 households with pet dogs were burglarized

First proportion

$p_{1} = \frac{x_{1} }{n_{1} } = \frac{10}{108} = 0.0925$

Given that a report on the nightly news broadcast stated that 20 out of 208 households without pet dogs were burglarized

Second proportion

$p_{2} = \frac{x_{2} }{n_{2} } = \frac{20}{208} = 0.0961$

where

$P = \frac{n_{1}p_{1} +n_{2}p_{2} }{n_{1} +n_{2} }$

P = 0.09486

Q = 1 - P = 1 - 0.09486 = 0.90514

<u><em>Step(ii):-</em></u>

Test statistic

$Z = \frac{p_{1}-p_{2} }{\sqrt{PQ(\frac{1}{n_{1} } +\frac{1}{n_{2} } )} }$

$Z = \frac{0.0925-0.0961 }{\sqrt{0.09486 X 0.90514(\frac{1}{108 } +\frac{1}{208 } )} }$

Z = -0.1040

|Z| = |-0.1040|

|Z| = 0.1040

Critical value Z = 1.96 at 0.05 level of significance
