A psychologist is interested in the mean IQ score of a given group of children. It is known that the IQ scores of the group have a standard deviation of 10. The psychologist randomly selects 100 children from this group and finds that their mean IQ score is 100. Based on this sample, find a 99% confidence interval for the true mean IQ score for all children of this group. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place. (If necessary, consult a list of formulas.)

Answers

Answer:

The 99% confidence interval for the true mean IQ score for all children of this group is (97.4, 102.6). The lower limit is 97.4 and the upper limit is 102.6.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.99}{2} = 0.005[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.005 = 0.995[/tex], so Z = 2.575.

Now, find the margin of error M as such

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

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

[tex]M = 2.575\frac{10}{\sqrt{100}} = 2.575[/tex]

Rounding to one decimal place, the margin of error is 2.6.

The lower end of the interval is the sample mean subtracted by M. So it is 100 - 2.6 = 97.4.

The upper end of the interval is the sample mean added to M. So it is 100 + 2.6 = 102.6.

The 99% confidence interval for the true mean IQ score for all children of this group is (97.4, 102.6). The lower limit is 97.4 and the upper limit is 102.6.

Find Y
Special right triangles
Please last question of the day!! Due very soon

Answers

Given:

A right triangle with angles 30, 60, 90 degrees.

Hypotenuse = [tex]2\sqrt{2}[/tex] mm.

Base = y

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]

[tex]\cos (60^\circ)= \dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{1}{2}=\dfrac{y}{2\sqrt{2}}[/tex]

[tex]\dfrac{2\sqrt{2}}{2}=y[/tex]

[tex]\sqrt{2}=y[/tex]

Therefore, the value of y is [tex]\sqrt{2}[/tex] mm.

Answers

The value of the angle theta is 58 degrees

How to determine the value of the angle theta

From the question, we have the following parameters that can be used in our computation:

Sin 0=0.85

Express the angle in the equation properly

So, we have the following representation

sin(Ф) = 0.85

Take the arc sin of both sides of the equation

So, we have the following representation

sin⁻¹(sin(Ф)) = sin⁻¹(0.85)

Evaluate the arc sin of one side of the equation

So, we have the following representation

Ф = sin⁻¹(0.85)

Evaluate the arc sin of the other side of the equation

So, we have the following representation

Ф = 58.2116693829

Approximate the equation

Ф = 58 degrees

Hence, the solution is 58 degrees

Find two consecutive odd numbers such that the difference between their reciprocals is 2/99.

note (the answer key said 9 and 11 and after testing it, it was correct, but I don't know how to get that answer)
Note (the chapter name is fractional equations, so they want us to make an equation and solve it)

Answers

The two consecutive odd numbers such that the difference between their reciprocals is of 2/99 are given as follows:

9 and 11.

How to obtain the numbers?

The two numbers are odd numbers and consecutive, hence they are symbolized as follows:

n and n + 2. (as n + 1 is even).

Their reciprocals are given as follows:

1/n.1/(n + 2).

The difference of their reciprocals is obtained as follows:

1/n - 1/(n + 2) = 2/99.

The least common factor of n and n + 2 is of n x (n + 2), hence:

(n + 2 - n)/[n(n + 2)] = 2/99

2/[n(n + 2)] = 2/99.

As the numerators are equal, we take the denominators to solve for n as follows:

n(n + 2) = 99.

n² + 2n - 99 = 0.

(n - 9)(n + 11) = 0.

Applying the Factor Theorem, the solutions are given as follows:

n - 9 = 0 -> n = 9.n + 11 = 0 -> n = -11.

We want the positive numbers, hence the numbers are:

n = 9 and n + 2 = 9 + 2 = 11.

Answers

Answer:

True, 50 tens times hundreds equal 40 tens times 5 hundreds

Step-by-step explanation:

50 tens times 4 hundreds equals to 40 ten times 5

hundreds because if you multiply 50 by 4 hundreds

you'll get 20,000 and if you multiply 40 tens by

hundred it will still give you 20,000

50 × 400 = 40 × 500

is 11^2 x 5^4 a factor of 11^3 x 5^4

Answers

No, 11^2 x 5^4 is not a factor of 11^3 x 5^4.

To see this, you can divide 11^3 x 5^4 by 11^2 x 5^4 and see that there is a remainder.

11^3 x 5^4 = (11 x 11 x 11) x (5 x 5 x 5 x 5)

= 121 x 625

= 75125

11^2 x 5^4 = (11 x 11) x (5 x 5 x 5 x 5)

= 121 x 625

= 75125

75125 / 75125 = 1 with a remainder of 0.

Therefore, 11^2 x 5^4 is not a factor of 11^3 x 5^4.

A particle moves with velocity function v(t) = −t2 + 5t − 3, with v measured in feet per second and t measured in seconds. Find the acceleration of the particle at time t = 3 seconds.

Answers

The acceleration of the particle is 1 foot per second square

How to determine the acceleration of the particle?

From the question, we have the following parameters that can be used in our computation:

Velocity function v(t) = −t2 + 5t − 3

Express properly

So, we have

v(t) = -t² + 5t − 3

At time t = 3 seconds, we have

v(3) = -(3)² + 5(3) − 3

Evaluate

v(3) = 3

So, we have

Acceleration = v(3)/3

This gives

Acceleration = 3/3

Evaluate

Acceleration = 1 foot per second square

Hence, the acceleration is 1 foot per second square
