Scores on an IQ test are normally distributed. A sample of 25 IQ scores had standard deviation of 8. The developer of the test claims that the population standard deviation of 15. Do these data provide sufficient evidence to significance? Use =0.05α=0.05 . Test by using a confidence interval. Show step1-step3.

Answers

Answer:

Yes, the data provides sufficient evidence at 0.05 level of significance

Step-by-step explanation:

n = 25

s = 8

σ = 15

χ² = (n - 1)s² / σ²

χ² = (25 - 1)*8² / 15²

χ² = (24 * 64) / 225

χ² = 6.827

The critical value at 0.05 ; df = 25 - 1 = 24

12.4012 and 39.3641

Reject H0 if χ² < 12.4012 or if χ² > 39.3641

Since,

χ² < 12.4012 ; We reject H0 ;

Simplify.
Multiply and remove all perfect squares from inside the square roots. Assume b is positive.

Answers

Answer:

216*b^2

Step-by-step explanation:

first, remember that:

a*√b = √(a^2*b)

√a*√b = √(a*b)

[tex]b^n*b^m = b^{n + m}[/tex]

[tex](b^n)^m = b^{n*m}[/tex]

Now, our expression is:

[tex]2*\sqrt{8*b^3} *9*\sqrt{18*b} = (2*9)*\sqrt{8*b^3}*\sqrt{18*b}[/tex]

Where in the right I rewrite the expression so it is easier to work.

Now we can use the second property of the above ones, to have:

[tex]18*\sqrt{8*b^3*18*b} = 18*\sqrt{(8*18)*b^{3 + 1}} = 18*\sqrt{144*b^4}[/tex]

And we know that:

[tex]\sqrt{x} = x^{1/2}[/tex]

Then:

[tex]18*\sqrt{144*b^4} = 18*(144*b^4)^{1/2} = 18*\sqrt{144}*(b^4)^{1/2}[/tex]

and 12*12 = 144, then:

[tex]18*\sqrt{144}*b^{4*1/2} = 18*12*b^2 = 216*b^2[/tex]

Slope of the line and y- intercept

Answers

Answer:

-3/2 is the slope

0 is the y-intercept

Step-by-step explanation:

Start at the dot to the very left since that's where it starts. Rise/Run so first start by going down to where the line meets a place where a dot can be placed. If you go down 3 and run over 2. You get to another dot that can be placed. (Place dots where the line meets a dot in the grid if that makes sense). Also if you go down another 3 and run another 2, you get to your next coordinate. The y=intercept is just basically where the line meets the y-axis so in this case, it's 0.

It costs $45 for 3 xylophones and 3 yo-yo's. If you purchased 5 xylophones and
6 yo-yo's, it would cost $80. Set up a system of equations and solve for the
cost of a single xylophone and a single yo-yo.

Answers

Step-by-step explanation:

xylophone : x

yo-yo : y

3x + 3y = 45 —(1)

5x + 6y = 80 —(2)

(1)*2 : 6x + 6y = 90 —(3)

(3)-(2):

6x + 6y = 90

-(5x + 6y) = 80

x =10 — (4)

Sub (4) into (1)

3(10) + 3y = 45

30 + 3y = 45

3y = 45-30

y = 15/3

y = 5

Step-by-step explanation:

The gates of an amusement park are closely monitored to determine whether the number of
people in the amusement park ever poses a safety hazard.
On a certain day, the rate at which people enter amusement park is modeled by the function
e(x) = 0.03x3 + 2, where the rate is measured in hundreds of people per hour since the gates
opened. The rate at which people leave the amusement park is modeled by the function
l(x) = 0.5x + 1, where the rate is measured in hundreds of people per hour since the gates
opened.
What does (e – l)(4) mean in this situation?

Answers

Answer:

Maybe how many people are in the park

For given situation, (e - l)(4) means, there are 92 people in the amusement park 4 hours after the gates open.

What is a function?

"It is an expression that defines a relationship between one variable and another variable."

For given example,

the rate at which people enter amusement park is modeled by the function

[tex]e(x) = 0.03x^3 + 2[/tex]

where the rate is measured in hundreds of people per hour since the gates opened.

The rate at which people leave the amusement park is modeled by the function

[tex]l(x) = 0.5x + 1[/tex]

where the rate is measured in hundreds of people per hour since the gates opened.

First we find the subtraction of functions [tex](e-l)(x)[/tex].

[tex]\Rightarrow (e-l)(x)=e(x)-l(x)\\\\\Rightarrow (e-l)(x)=0.03x^3 + 2-(0.5x + 1)\\\\\Rightarrow (e-l)(x)=0.03x^3+2-0.5x-1\\\\\Rightarrow (e-l)(x)=0.03x^3-0.5x+1[/tex]

For x = 4,

[tex]\Rightarrow (e-l)(4)=0.03(4)^3-0.5(4)+1\\\\\Rightarrow \bold{(e-l)(4)=0.92}[/tex]

As, the rate is measured in hundreds of people per hour

So, (e - l)(4) means, there are 92 people in the amusement park 4 hours after the gates open.
