_____ is a tort in which the presumption of negligence arises because the defendant was in exclusive control of the situation, and the plaintiff would not have suffered injury but for someone's negligence.

Res ipsa loquitur is a doctrine in law that one can presume the negligence of a defendant when the facts are glaring.The doctrine has primarily required that a defendant have exclusive power over the occurrence of an injury. negligence could result from

1. an actual causal connection between the defendant's conduct and the resulting harm; 2 a duty of care owed by the defendant to the plaintiff; 3 a breach of that duty;

Melanie is working in a laboratory and spills a bottle of reagent which sources would most likely tell her how to clean the spil

I am Lyosha [343]

<span>The lab teacher would be one resource that could be asked, since they are likely experienced in the use and disposal of the reagent. Also, in other instances, the Material Safety Data Sheets could be accessed, since they will have all the steps required for handling, disposal, and cleaning of the reagent, and any hazards that need to be accounted for in the cleaning-up process.</span>

A university officer wants to know the proportion of registered students that spend more than 20 minutes to get to school. He se

vlada-n [284]

Answer:

1) We need a random sample. For this case we assume that the sample selected was obtained using the simple random sampling method.

2) We need to satisfy the following inequalities:

$n\hat p =25*0.52= 13 \geq 10$

$n(1-\hat p) = 25*(1-0.52) =12 \geq 10$

So then we satisfy this condition

3) 10% condition. For this case we assume that the random sample selected n represent less than 10% of the population size N . And for this case we can assume this condition.

So then since all the conditions are satisfied we can conclude that we can apply the normal approximation given by:

$p \sim N (\hat p, \sqrt{\frac{\hat p (1-\hat p)}{n}})$

So then the answer for this case would be:

a. Yes.

Explanation:

For this case we assume that the question is: If in the experiment described we can use the normal approximation for the proportion of interest.

For this case we have a sample of n =25

And we are interested in the proportion of registered students that spend more than 20 minutes to get to school.

X = 13 represent the number of students in the sample selected that have a time more than 20 min.

And then the estimated proportion of interest would be:

$\hat p = \frac{X}{n}= \frac{13}{25}= 0.52$

And we want to check if we can use the normal approximation given by:

$p \sim N (\hat p, \sqrt{\frac{\hat p (1-\hat p)}{n}})$

So in order to do this approximation we need to satisfy some conditions listed below:

1) We need a random sample. For this case we assume that the sample selected was obtained using the simple random sampling method.

2) We need to satisfy the following inequalities:

$n\hat p =25*0.52= 13 \geq 10$

$n(1-\hat p) = 25*(1-0.52) =12 \geq 10$

So then we satisfy this condition:

3) 10% condition. For this case we assume that the random sample selected n represent less than 10% of the population size N . And for this case we can assume this condition.

So then since all the conditions are satisfied we can conclude that we can apply the normal approximation given by:

$p \sim N (\hat p, \sqrt{\frac{\hat p (1-\hat p)}{n}})$

So then the answer for this case would be:

a. Yes.
