Answer:

The answer is below

Explanation:

Probability distribution are statistical function that shows all the possible outcomes of a random variable within a given range of values.

a) The mean ( $\bar x$ ) of a probability distribution of a discrete random variable is:

$\bar x=\Sigma\ [xP(x)]$ = (0 * 0.8) + (1 * 0.15) + (2 * 0.04) + (3 * 0.01) = 0.26

b) The standard deviation (σ) of a probability distribution of a discrete random variable is:

$\sigma=\sqrt{ \Sigma\ [(x-\bar x)^2*P(x)]}\\\\\sigma=\sqrt{(0-0.26)^2*0.8+(1-0.26)^2*0.15+(2-0.26)^2*0.04+(3-0.26)^2*0.01} \\\\\sigma=0.577$

The Bureau of Transportation Statistics Omnibus Household Survey is conducted annually and serves as an information source for t

sasho [114]

Answer:

a) For this case we have quantitative data since we have frequencies per each category.

b) For this case is better use percentages since we have frequency counts per each

c) First we need to calculate the total for the frequencies:

$Total = 44+130+165+741= 1080$ respondents

For this case we can calculate the percentage like this:

$\% Strongly_{agree} = \frac{44}{1080} *100 =4.07\%$

d) For this case the percentage of people who agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving is just 4.07% and by the other hand the rest of the people correspond to 95.93%.

$\frac{1036}{44}=23.55$

The people who are NOT strongly agree is about 24 times greater than the peopl who strongly agrees.

So we can say that we don't have a general support for the claim.

Explanation:

For this case we have the following data given:

Number of respondents that they strongly agree with the statement = 44

Number of respondents that they somewhat agree with the statement = 130

Number of respondents that they somewhat disagree agree with the statement = 165

Number of respondents that they strongly disagree agree with the statement = 741

Part a

Do the responses for this statement provide categorical or quantitative data?

For this case we have quantitative data since we have frequencies per each category.

Part b

Would it make more sense to use averages or percentages as a summary of the responses for this statement?

For this case is better use percentages since we have frequency counts per each category so then not makes sense calculate averages for this case.

Part c

What percentage of respondents strongly agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving?

First we need to calculate the total for the frequencies:

$Total = 44+130+165+741= 1080$ respondents

For this case we can calculate the percentage like this:

$\% Strongly_{agree} = \frac{44}{1080} *100 =4.07\%$

Part d

For this case the percentage of people who agree with allowing drivers of motor vehicles to talk on a hand-held cell phone while driving is just 4.07% and by the other hand the rest of the people correspond to 95.93%.

$\frac{1036}{44}=23.55$

The people who are NOT strongly agree is about 24 times greater than the peopl who strongly agrees.

So we can say that we don't have a general support for the claim.

State the elements of proof that are necessary to make out a case of attractive nuisance as per the Restatement of Torts, Sectio

Ivan

Answer:

Attractive nuisance occurs when a child trespasses a property because something in the land attracted him, e.g. an old wagon or car, an gets hurt by playing with it. The requirements for attractive nuisance to exist are:

The child is hurt by playing with the object or structure that attracted him/her (the object must be man made).
The person in charge of the place should have reasonably known that the object or structure could attract children.
The person in charge of the place should have known that playing with the object or structure could pose a risk for children.
The child needs to be young enough to not understand the risk of playing with the object or structure, e.g. someone 17 years old is not considered a young child though he/she is a minor.
The risk associated with the object or structure is far greater than any decorative use given to the object or structure.
The person in charge of the place failed to do enough to prevent the danger or protect any children that would eventually play with the object or structure, e.g. put a fence around it.
