A sports club tests its players for steroid usage with a test that gives a positive reading 93% of the time when administered to a steroid user and gives a negative reading 96% of the time when administered to a player who does not use steroids. It is known that 8% of the players are steroid users. Draw a probability tree diagram for the given problem.
What is the probability that a player does not use steroids, given that the person had a positive reading on the test? Round your answer to four decimal places.
Answers
Answer:
P(no steroid user / positive reading on test) = 0.3309
Step-by-step explanation:
Computation:
Bayes' Theorem:
P(A / B) = P(A and B) / P(B)
P(no steroid user / positive reading on test) = P(no steroid user and positive) / P(positive)
P(no steroid user / positive reading on test) = (0.92 x 0.04)/(0.08 x 0.93 + 0.92 x 0.04)
P(no steroid user / positive reading on test) = 0.3309
The probability that a player does not use steroids, given that the person had a positive reading on the test is 0.3309.
Calculation of the probability:Since A sports club tests its players for steroid usage with a test that gives a positive reading 93% of the time when administered to a steroid user and gives a negative reading 96% of the time when administered to a player who does not use steroids. It is known that 8% of the players are steroid users.
So, here the probability should be
P(no steroid user / positive reading on test) = (0.92 x 0.04)/(0.08 x 0.93 + 0.92 x 0.04)
= 0.3309
Hence, The probability that a player does not use steroids, given that the person had a positive reading on the test is 0.3309.

Assume a recent sociological report states that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101. Suppose Jason, a policy manager at a local university, decides to take a random sample of 125 university students to survey them about their drinking habits. Determine the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption. Provide your answer with precision to two decimal places.
Answers
Answer:
4.10
0.17
Step-by-step explanation:
From the question, we know that
A recent sociological report stated that university students drink 4.10 alcoholic drinks per week on average, with a standard deviation of 1.9101.
Also, we're tasked with finding the mean and standard deviation of the sampling distribution of the sample mean alcohol consumption.
To find the mean of the sampling distribution, we take the sample mean of the same of that university students as a direct substitute. This then means that the mean of the sampling distribution of the sample mean alcohol consumption is 4.10 alcoholic drinks per week on average.
On the other hand, the standard deviation of the sampling distribution of the sample mean alcohol consumption is taken to be the division of the standard deviation of the sample mean. Mathematically, we have
Standard Deviation, S = 1.9101 / √125
Standard Deviation, S = 1.9101 / 11.18
Standard Deviation, S = 0.17
Therefore, the Standard Deviation is 0.17
Answer:
The values are
[tex]\mu_{\= x } = \mu = 4.10[/tex]
And
[tex]\sigma _{\= x} = 0.38202[/tex]
Step-by-step explanation:
The population mean is [tex]\mu = 4.10[/tex]
The standard deviation is [tex]\sigma = 1.9101[/tex]
The sample size is n = 125 students
Generally the mean of the sampling distribution of the sample mean is equivalent to the population mean
i.e [tex]\mu_{\= x } = \mu = 4.10[/tex]
Generally the standard deviation of the sampling distribution of the sample mean alcohol consumption is mathematically represented as
[tex]\sigma _{\= x} = \frac{\sigma }{\sqrt{n} }[/tex]
=> [tex]\sigma _{\= x} = \frac{1.9101 }{\sqrt{125} }[/tex]
=> [tex]\sigma _{\= x} = 0.38202[/tex]

Records on a fleet of trucks reveal that the average life of a set of spark plugs is normally distributed with a mean of 22,100 miles. A manufacturer of spark plugs claims that its plugs have an average life in excess of 22,100 miles. The fleet owner purchased 18 sets and found that the sample average life was 23,400 miles, the sample standard deviation was 1,500 miles and the computed test statistic was 3.677. Based on these findings, there is enough evidence to accept the manufacturer's claim at the 0.05 level.
Answers
Answer:
There no sufficient evidence to support the manufactures claim at the 0.05 level
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 22100 \ miles[/tex]
The sample mean is [tex]\= x = 23400 \ miles[/tex]
The sample size is [tex]n = 18[/tex]
The standard deviation is [tex]\sigma = 1 500 miles[/tex]
The test statistics is [tex]t = 3.677[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 22100[/tex]
The alternative hypothesis is [tex]H_a : \mu \ne 22100[/tex]
Generally the p-value is mathematically represented as
[tex]p-value = 2 * P(t >3.677 )[/tex]
From the z-table [tex]P(t >3.677 ) = 0.000118[/tex]
So
[tex]p-value = 2 * 0.000118[/tex]
=> [tex]p-value = 0.000236 [/tex]
From he value given and obtained we see that [tex]p-value < \alpha[/tex]
Hence we reject the null hypothesis
Hence there no sufficient evidence to support the manufactures claim

Answers
Step-by-step explanation:
The answer should be A.
We can start with the fact that x = cos t, y = sin t traces the unit circle counterclockwise once every 2π radians, starting at (1, 0).
By starting at t = π instead of t = 0, we move the starting point to (-1, 0) without changing the direction.
All 5 options have the correct starting point (except D) and number of rotations, but only option A is counterclockwise.

You buy milk that contains 180 calories per 2 cups. Use a ratio table to find the number of calories in 18 cups.
Answers
Answer:
1620
Step-by-step explanation:
180/2=90
90*18=1620
You buy milk with 180 calories in two glasses. Now compute the caloric value of 18 cups. 18 cups contain 1620 calories.
What is meant by caloric value?Calorific value, also known as heating value or heat of combustion, is a unit of measurement for the total energy content produced in the form of heat when a substance is completely combusted with air or oxygen. The amount of heat energy released during complete combustion of a unit mass of a fuel is defined as its calorific value. It is measured in kJ/kg.It is the measurement of the heat value or amount of energy released, and it is expressed in either gcv or ncv. Gross calorific value (GCV), also known as Higher Heating Value (HCV), is the amount of heat released by complete combustion when a unit of fuel is burned.Therefore,
You buy milk with 180 calories in two glasses.
Now compute the caloric value of 18 cups.
Let 18 cups have a calorie count of As, and 2 cups have 180 calories.
A serving of two cups contains 180 calories.
As a result, the ratio would be 2: 180.
As a result, 18 cups contain X calories.
18 cups are equal to X calories.
Consequently, the ratio would be X : 18
We now set a ratio to determine how many calories are in 18 cups:
2 : 180 :: 18 : X
Simplifying,
2/ 180 = 18/X
Cross multiplying results in:
2X = 18 × 1 80
= 3240
By multiplying both sides by 2, we obtain:
X = 3240/2
= 1620
Hence, 18 cups have 1620 calories in them.
