Of the 64 people who answered "yes" to a question, 6 were male. Of the 70 people that answered "no" to the question, 8 were male. If one person is selected at random from the group, what is the probability that the person answered "yes" or was male?

Answers

Answer:

The probability that the person answered "yes" or was male is 0.537

Step-by-step explanation:

The union of events is equivalent to the disjunction "or". Given two events A and B, the union of events, denoted by A∪B, is defined as the event formed by all the elements that are in A or B. That is, the event A∪B is verified when one of the two or both occurs.

Considering two events A and B with probabilities P (A) and P (B), respectively, the probability of their union is given by:

P(A∪B)= P(A) + P(B) - P(A∩B)

In this case:

A: the person answered "yes" B: the person was male

So, being the probability calculated as the number of favorable cases divided by the total number of possible cases, then in this case it is known that the number of people who answered yes is 64, while the number of people who responded is not 70. Therefore , the total number of people who answered is equal to 64 + 70 = 134. So, the probability of answering yes is:

P(A)=[tex]\frac{64}{134}[/tex]=0.478

On the other hand, you know that out of 64 people who answered yes, the number of being male is 6. And out of 70 people who answered no, the number of being male is 8. So the probability that men answer yes is calculated as:

P (A∩B) =[tex]\frac{6}{134}[/tex]= 0.045

Finally, with the total number of men equal to 6 + 8 = 14, the probability of being male is:

P(B)=[tex]\frac{14}{134}[/tex] = 0.104

Then:

P(A∪B)= P(A) + P(B) - P(A∩B)

P(A∪B)= 0.478 + 0.104 - 0.045

Solving:

P(A∪B)= 0.537

The probability that the person answered "yes" or was male is 0.537

A recent study has shown that 10% of computer science concentrators suffer from symptoms of Carpal Tunnel Syndrome. Researchers have developed a diagnostic test for this condition and in a recent trial, the test gave a positive result in 96% of the patients who were known to truly have Carpal Tunnel Syndrome.
a) For an initial version of the diagnostic test, the false positive rate (the percentage of people without Carpal Tunnel who incorrectly test positive) was 44%. If a student received a positive result from this test, what would be the posterior probability that they truly have Carpal Tunnel Syndrome?
b) The researchers believe their test will be practically useful if a positive result implies the student has Carpal Tunnel with at least 75% probability. What is the largest possible false positive rate that would achieve this accuracy target?

Answers

Answer:

1. 0.1951

2. 3.56%

Step-by-step explanation:

Probability of disease = 0.10

Probability of disease and positive = 0.96

Probability of no disease and positive = 0.44

Probability of disease and positive result = 0.10x0.96/0.10x0.96+0.90x0.44

= 0.096/0.096+0.396

= 0.096/0.492

= 0.1951

Probability of disease false positive result

P(disease|positive result)

= (0.10x0.96/0.10x0.96+0.90xP) >= 0.75

= 0.096/0.096+0.90p >= 0.75

We cross multiply

0.096 >= 0.75(0.096+0.90p)

0.096 >= 0.072 + 0.675p

0.096-0.072 >= 0.675p

0.024 >= 0.675p

Answer:

The margin of error for the 94% confidence interval is 0.6154.

Step-by-step explanation:

The (1 - α)% confidence interval for population mean is:

[tex]CI=\bar x\pm z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

The margin of error of this interval is:

[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

The critical value of z for 94% confidence level is, z = 1.88.

Compute the margin of error for the 94% confidence interval as follows:

[tex]MOE=z_{\alpha/2}\cdot\frac{\sigma}{\sqrt{n}}[/tex]

[tex]=1.88\times\frac{3}{\sqrt{84}}\\\\=0.6154[/tex]

Thus, the margin of error for the 94% confidence interval is 0.6154.

Answer:

probability that student passes = 0.7815

Step-by-step explanation:

Given:

Student studies = 85% = 0.85

Student not study = 11% = 0.11

Student who pass = 90% = 0.90

Computation:

P(student not pass) = 1 - 0.85

P(student not pass) = 0.15

probability that student passes = P(Student studies)(Student who pass) + P(Student not study)(student not pass)

probability that student passes = (0.85)(0.90) + (0.15)(0.11)

probability that student passes = 0.765 + 0.0165

probability that student passes = 0.7815

Using the percentages given, it is found that there is a 0.7815 = 78.15% probability that student passes.

The percentages associated with passing the test are given by:

90% of 85%(student studies for the test).11% of 15%(student does not study for the test).

Hence, adding these percentages:

[tex]p = 0.9(0.85) + 0.11(0.15) = 0.7815[/tex]

0.7815 x 100% = 78.15%

There is a 0.7815 = 78.15% probability that student passes.

whats the question?

Step-by-step explanation:

The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation

h = -16t2 + h0, where h0 is the initial height of the object. Suppose a small rock dislodges from a ledge that is 255 ft above a canyon floor. Solve the equation h = -16t2 + 255 for t, using the quadratic formula to determine the time it takes the rock to reach the canyon floor.

t 0.87 s

t 4 s

t = 8.5 s

t = 16 s

Answers

Answer:

B on edge 2022

Explanation:

Picture:

The time it takes the rock to reach the canyon floor is 8.5 seconds.

Option C is the correct answer.

What is an equation?

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

Using the quadratic formula.

t = (-b ± √(b² - 4ac)) / 2a

where a = -16, b = 0, and c = 255.

Now,

Plugging in the values.

t = (-0 ± √(0² - 4(-16)(255))) / 2(-16)

t = (± √(16320)) / (-32)

t = (± 128) / (-32)

So,

The solutions for t.

t = 4 seconds (taking the negative solution)

t = 8.5 seconds (taking the positive solution)

We can eliminate t = 0.87 seconds and t = 16 seconds as they are not solutions to the equation.

Therefore,

The time it takes the rock to reach the canyon floor is 8.5 seconds.
