In Test A, suppose you make 100 experimental measurements of some quantity and then calculate mean, standard deviation, and stan

dard error of the numbers you obtain. In Test B, suppose you make 1000 experimental measurements of the same quantity and you again calculate mean, standard deviation, and standard error. How would you expect the mean, standard deviation, and standard errors found in Test A and Test B to compare?

Answer:

D. I would expect the means and standard deviations in the two tests to be about the same, but the standard error in Test B should be smaller than in Test A.

Step-by-step explanation:

Options Includes <em>"A.) I would expect the means, the standard deviations, and the standard errors in Test A and Test B to be about the same.</em>

<em>B.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be smaller than in Test A .</em>

<em>C.) I would expect the means of the two tests to be about the same, but both the standard deviation and the standard error in Test B should be bigger than in Test A .</em>

<em>D.) I would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be smaller than in Test A.</em>

<em>E.) would expect the means and standard deviations in the two test to be about the same, but the standard error in Test B should be larger than in Test A.</em>

<em />

Reason:

Since we are measuring the same quantity 100 times and 1000 times respectively in both the tests, we would expect the means and standard deviations to not be significantly different from each other. The standard errors would differ, though, since the formula is = Standard deviation/square root of sample size. Since the sample sizes of both the tests are so significantly different, the corresponding standard errors will also be significantly different. More specifically, the standard error of Test B will be smaller than that of Test A.

Four farmers are picking apples in an orchard. Farmer A picks 38 of the apples, Farmer B picks 22% of the apples, Farmer C picks
AfilCa [17]
The amount of apples picked by the farmers is:
Farmer A=38%=0.38
Farmer B=22%=0.22
Farmer C=0.29
Farmer D=0.2
Thus the order from the least to greatest by th number of apples they pick will be:
D,B,C,A
that is:
Farmer D, Farmer B, Farmer C, Farmer A

A sample of carbon dioxide occupies a volume of 3.50 l at 125 kpa pressure. what pressure would the gas exert if the volume was
Novosadov [1.4K]

The gas exerts a pressure of 218.75 kPa when its volume is reduced to 2.0 L, following the behavior of an ideal gas.

Ideal gas behavior:

Suppose the initial volume of carbon dioxide gas is V = 3.5l

Initial pressure is P = 125 kPa

Since the volume is reduced to 2.0l, the final volume is shown as V'= Will be done. 2L

The final pressure of the gas is P'.

We consider the behavior of gas to be ideal. From the ideal gas equation, it becomes as follows.

PV = P'V'

125 × 3.5 = P'× 2

P'= 218.75 kPa

Therefore, the final pressure is 218.5 kPa.

Three pounds of soil will fill 8 flower pots. You can use that information to answer different questions. Drag each expression t
Sladkaya [172]

Answer:

Left-Most Box:

3\div 8\text{ and } \frac{1}{8}\text{ of } 3

Middle Box:

=\frac{1}{3}\text{ of } 8\text{ and } =\frac{1}{3}\times 8

Right-Most Box:

8+\frac{1}{3}\text{ and } 8\times 3

Step-by-step explanation:

We know that 3 pounds of soil fills 8 flower pots.

Using this, we can find our answers to different questions.

Question 1:

We want to know how many pots of soil will fill 1 flower pot.

We know that 3 pounds of soil fills 8 pots. So, to find the amount of soil that fills 1 pot, we can divide 3 by 8:

3\div 8

This is the same as multiplying by a fraction. Namely, is it also 1/8 of 3:

=\frac{1}{8}\text{ of } 3

And these are all the choices for the first question.

Question 2:

We want to know how many pots we can fill with 1 pound of soil.

To find this, we can divide 8 pots by 3 to get the unit rate of pots to soil. So:

8\div3

This is the same as 1/3 of 8:

=\frac{1}{3}\text{ of } 8

Which is the same as 1/3 multiplied by 8:

=\frac{1}{3}\times 8

And these are all of the possible choices.

Question 3:

The two remaining ones,

8+\frac{1}{3}\text{ and } 8\times 3

Will go here.
