Find the slope of the line that passes through the given two points.
Mumz [18]

Answer:

Step-by-step explanation:

The slope formula is used to calculate the slope if you are given two points. Remember that slope is defined as rise/run. Which translates to the rise divided by the run. The slope formula will allow us to take the change in the rise and divide by the change in the run.

Answer:

0.057258

Step-by-step explanation:

From the statement of the problem, the following information were given:

  • P(Positive|HIV)=0.979
  • P(Negative|No HIV)=0.919
  • P(HIV)=0.005

The following can be derived:

  • P(Positive|No HIV)=1-P(Negative|No HIV)=1-0.919=0.081
  • P(No HIV)=1-P(HIV)=1-0.005=0.995

We are to determine the probability that a person has HIV given that they test positive. [P(HIV|Positive)]

Using Baye's theorem for Conditional Probability

P(HIV|Positive)=\dfrac{P(Positive|HIV)P(HIV)}{P(Positive|HIV)P(HIV)+P(Positive|No HIV)P(No HIV)}=\dfrac{0.979*0.005}{0.979*0.005+0.081*0.995}

P(HIV|Positive)=0.057258

The probability that a random person tested has HIV given that they tested positive is 0.057258.

My name is Ann [436]

The statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.

<h3>What is a survey?</h3>

A survey is a means of gathering information from a sample of people using pertinent questions with the goal of understanding populations as a whole.

We have an automotive service centre would like feedback on its customer service each customer receives a printed card after they pay for services with a short survey on which customer service is ranked on a scale from 1  to 5.

From the data given we can say, not everyone will choose to leave a review when leaving the store, and those who do will have been inconvenienced in some way and felt compelled to do so, while the rest of the customers left and went about their business.

Thus, the statement second "this is nonresponse bias because many customers may choose to not fill out the cards" would be the best choice.
