An IQ test is designed so that the mean is 100 and the standard deviation is 19 for the population of normal adults. Find the sample size necessary to estimate the
mean IQ score of statistics students such that it can be said with 95% confidence that the sample mean is within 7 IQ points of the true mean. Assume that o = 19 and
determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation.

Answers

Step-by-step explanation:

To solve this question, we use this formula:

x± s t_(1−c)/2 / √n = 5

(1 - c)/2 = (1 - 0.95) / 2 = 0.025

Using a t score calculator at this value, at the 95% confidence internval,

t = 0.5080, So

100 - 19(0.5080) / √n = 5

Solving for n

n = 97

a) 97

b) yes

Which BEST describes the association between goals by the Red Team and the Blue Team?
A
nonlinear association
B
positive association
С

D

Answers

b positive association

The relation between the Red team and Blue team will be a non-linear association. Then the correct option is A.

What is the linear system?

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

The table is shown below.

The association between the goals of the Red Team and the Blue Team will be given in the table.

Let the line passes through the point (1, 1) and (4, 9). Then we have

y - 1 = 8/3(x - 1)

y - 3 = 8x - 8

    y = 8x - 5

But all the points present between the (1, 1) and (4, 9) do not lie on the line. Then the relation between the Red team and the Blue team will be a non-linear association.

What is the slope of the following equation?

y = -5x -2

Answers

M=-5, b=-2 hope this helps

Answer:

-5

Step-by-step explanation:

The slope of the graph is how much the line is changing. In this case, every time your x increases by one, your y decreases by -5. This is the case no matter what value the -2 is.

the general equation for a straight line is

y = mx + b

where m is the slope and b is the y-intercept, or the value of y when x is 0.

5. Find the perimeter and area of the parallelogram. Round to the nearest tenth if necessary.

Answers

Answer:

perimeter: 23.6yd

area: 34.3yd²

Step-by-step explanation:

This is technically a rectangle, but alrighty, so for the perimeter, you just add all the sides together, or multiply, blah blah blah, no here:

5.2 x 2 + 6.6 x 2 = 23.6

So the perimeter is 23.6yd

Now, we find the area by multiplying the width by the height (i think that's the right terminology, so you basically just multiply the only number's there:

5.2 x 6.6 = 34.32

But then we round to the tenth and 2 rounds down to 34.3, so the area is 34.3yd²

hope this helps:)

What is a logarithm?

Logarithms are another way of writing exponent. A logarithm with a number base is equal to the other number. It is just the opposite of the exponent function.

The expressions are given below.

[tex]\log _3 \dfrac{1}{3} \ and \ \log _b \dfrac{1}{b}[/tex]

This can be written as

[tex]\log _3 3^{-1} \\\\\log _bb^{-1}[/tex]

We know that the property of the logarithm

[tex]\log _a a = 1\\\\\log a^b = b\log a[/tex]

Then we have

[tex]\log _3 3^{-1} = -1 \log _33 = -1\\\\\log _bb^{-1} = -1 \log _bb = -1\\[/tex]

Wells [1898] But who shall dwell in these worlds if they be inhabited?Are we or they Lords of the World?And how are all things made for man? KEPLER (quoted in The Anatomy of Melancholy)BOOK ONE: THE COMING OF THE MARTIANSCHAPTER ONE: THE EVE OF THE WAR, excerptNo one would have believed in the last years of the nineteenth century that this world was being watched keenly and closely by intelligences greater than man's and yet as mortal as his own; that as men busied themselves about their various concerns they were scrutinised and studied, perhaps almost as narrowly as a man with a microscope might scrutinise the transient creatures that swarm and multiply in a drop of water. With infinite complacency men went to and fro over this globe about their little affairs, serene in their assurance of their empire over matter. It is possible that the infusoria under the microscope do the same. No one gave a thought to the older worlds of space as sources of human danger, or thought of them only to dismiss the idea of life upon them as impossible or improbable. It is curious to recall some of the mental habits of those departed days. At most terrestrial men fancied there might be other men upon Mars, perhaps inferior to themselves and ready to welcome a missionary enterprise. Yet across the gulf of space, minds that are to our minds as ours are to those of the beasts that perish, intellects vast and cool and unsympathetic, regarded this earth with envious eyes, and slowly and surely drew their plans against us. And early in the twentieth century came the great disillusionment.Yet so vain is man, and so blinded by his vanity, that no writer, up to the very end of the nineteenth century, expressed any idea that intelligent life might have developed there far, or indeed at all, beyond its earthly level. Nor was it generally understood that since Mars is older than our earth, with scarcely a quarter of the superficial area and remoter from the sun, it necessarily follows that it is not only more distant from time's beginning but nearer its end.The secular cooling that must someday overtake our planet has already gone far indeed with our neighbour. Its physical condition is still largely a mystery, but we know now that even in its equatorial region the midday temperature barely approaches that of our coldest winter. Its air is much more attenuated than ours, its oceans have shrunk until they cover but a third of its surface, and as its slow seasons change huge snowcaps gather and melt about either pole and periodically inundate its temperate zones. That last stage of exhaustion, which to us is still incredibly remote, has become a present-day problem for the inhabitants of Mars. The immediate pressure of necessity has brightened their intellects, enlarged their powers, and hardened their hearts. And looking across space with instruments, and intelligences such as we have scarcely dreamed of, they see, at its nearest distance only 35,000,000 of miles sunward of them, a morning star of hope, our own warmer planet, green with vegetation and grey with water, with a cloudy atmosphere eloquent of fertility, with glimpses through its drifting cloud wisps of broad stretches of populous country and narrow, navy-crowded seas.And we men, the creatures who inhabit this earth, must be to them at least as alien and lowly as are the monkeys and lemurs to us. The intellectual side of man already admits that life is an incessant struggle for existence, and it would seem that this too is the belief of the minds upon Mars. Their world is far gone in its cooling and this world is still crowded with life, but crowded only with what they regard as inferior animals. To carry warfare sunward is, indeed, their only escape from the destruction that, generation after generation, creeps upon them.In three to five complete sentences, explain why the inhabitants of Mars are interested in Earth.
