SAT verbal scores are normally distributed with a mean of 430 and a standard deviation of 120 (based on the data from the College Board ATP). If a sample of 15 students is selected randomly, find the probability that the sample mean is above 500. Does the central limit theorem apply for this problem?

Answers

Answer:

The value is [tex]P(X > 500 ) = 0.011942[/tex]

Step-by-step explanation:

From the question we are told that

The mean is [tex]\mu = 430[/tex]

The standard deviation is [tex]\sigma = 120[/tex]

The sample size is n = 15

Generally the probability that the sample mean is above 500

Gnerally the standard error of mean is mathematically represented as

[tex]s = \frac{\sigma }{ \sqrt{n} }[/tex]

=> [tex]s = \frac{ 120 }{ \sqrt{15} }[/tex]

=> [tex]s = 30.984[/tex]

Generally the probability that the sample mean is above 500

[tex]P(X > 500 ) = P( \frac{X - \mu }{\sigma_x} > \frac{500 - 430 }{ 30.984 } )[/tex]

[tex]\frac{X -\mu}{\sigma } = Z (The \ standardized \ value\ of \ X )[/tex]

[tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

=> [tex]P(X > 500 ) = P( Z > 2.259 )[/tex]

From the z table the area under the normal curve to the right corresponding to 2.259 is

[tex]P( Z > 2.259 ) = 0.011942[/tex]

=> [tex]P(X > 500 ) = 0.011942[/tex]

Is the equation 2x + 5 = 1 true, false, or open? Explain.

Answers

Answer:

open

Step-by-step explanation:

beacause

2x+5=1

2x=1-5

2x=-4

x=-4/2

x-2 so its open

An open statement is a statement that has an unknown variable

[tex]2x + 5 = 1[/tex] is an open statement

The equation is given as:

[tex]2x + 5 = 1[/tex]

From the equation, we have the following observations.

2, 5 and 1 are constants

x is a variable

Because the equation has a variable (i.e. x), then it is an open statement

Hence, [tex]2x + 5 = 1[/tex] is an open statement

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 17 minutes. What is the probability that it takes Isabella more than 5 minutes to wait for the bus

Answers

Answer:

P(X>5) = 0.857

Step-by-step explanation:

Let X [tex]\sim[/tex] uniform(3.17)

[tex]f(x) = \dfrac{1}{17-3} ; \ \ \ 3 \le x \le 17[/tex]

The required probability that it will take Isabella more than 5 minutes to wait for the bus can be computed as:

[tex]P(X > 5) = \int ^{17}_{5} f(x) \ dx[/tex]

[tex]P(X > 5) = \int ^{17}_{5} \dfrac{1}{17-3} \ dx[/tex]

[tex]P(X > 5) =\dfrac{1}{14} \Big [x \Big ] ^{17}_{5}[/tex]

[tex]P(X > 5) =\dfrac{1}{14} [17-5][/tex]

[tex]P(X > 5) =\dfrac{12}{14}[/tex]

P(X>5) = 0.857
