Answer:

\bar X = \frac{17+12+9+16+14}{5}= 13.6min

So then the best answer for this case would be:

a. 13.6 minutes

Explanation:

For this case we have the following data for the response rates:

17,12,9,16,14

And we want to calculate the mean response time for 911 calls in this village.

And for this case we use we can use the definition of sample mean given by:

\bar X = \frac{\sum_{i=1}^n X_i}{n}

Where n = 5 represent the sample size for this case. If we replace we got:

\bar X = \frac{17+12+9+16+14}{5}= 13.6min

So then the best answer for this case would be:

a. 13.6 minutes

The sample mean is an estimator unbiased of the population mean because:

E(\bar X) = E(\frac{\sum_{i=1}^n X_i}{n}) = \frac{1}{n} \sum_{i=1}^n E(X_i) = \frac{n\mu}{n}= \mu

For this reason is a good statistic if we want to see central tendency in a group of values.

ikadub [295]

Answer: a. Only one policy will pay, the premiums for the other contracts will be returned.

Explanation:

When there are multiple insurance contracts from the same insurer and these contracts have a ''Other Insurance With This Insurer'' provision, it means that in cases where the insured wants to claim, they can choose whichever of the policies they want and that one will pay out but they cannot pick them all.

The premiums paid on the other contracts/s will be returned to the insured because it represents excess coverage.

Reconstruction failed by most other measures: Radical Republican legislation ultimately failed to protect former slaves from white persecution and failed to engender fundamental changes to the social fabric of the South. When President Rutherford B. federalism debate that had been an issue since the 1790s almost mediately . Hayes removed federal troops from the South in 1877, former Confederate officials and slave returned to With the support of a conservative Supreme Court, these newly empowered white southern politicians passed black codes, voter qualifications, and other anti-progressive legislation to reverse the rights that blacks had gained during Radical Reconstruction. The U.S. Supreme Court bolstered this anti-progressive movement federalism  with decisions in the Slaughterhouse Cases, the Civil Rights Cases, and federalism United States v.

The U.S. Bureau of Economic Analysis​ (BEA) has recently adopted a new approach to calculate real GDP and real GDP growth to cor
pashok25 [27]

One of the features of the new approach is​ that, now BEA uses the geometric average of fixed weight indexes and uses two base years to calculate the growth rate of real GDP between two consecutive years.

Explanation:

In both actual and nominal GDP, the U.S. Economic Analysis Department results. It estimates the real United States. GDP is a fixed base year annual rate. Imports and international sales from American businesses and people are exempt.

GDP reflects the degree to which the economy generates production. Global warming is not generated and not part of GDP. The effect of environmental damage is not measured accurately. The loss should not be included in GDP and the calculation of environmental damage has not been accepted.

Lana71 [14]

Answer:

$880.72

Explanation:

Bond price will be calculated by following formula

Bond Price = C x [ ( 1 - ( 1 + r )^-n ) / r ] + [ F x ( 1 + r )^-n ]

Bond Price = $87 x [ ( 1 - ( 1 + 0.107 )^-10 ) / 0.107 ] + [ $1,000 x ( 1 + 0.107 )^-10 ]

Bond Price = $87 x [ ( 1 - ( 1.107 )^-10 ) / 0.107 ] + [ $1,000 x ( 1.107 )^-10 ]

Bond Price = $87 x [ ( 1 - ( 1.107 )^-10 ) / 0.107 ] + [ $1,000 x ( 1.107 )^-10 ]

Bond Price = $518.87 + $361.85

Bond Price = $880.72
