To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians

yKpoI14uk [10]

The standard error of the difference of sample means is 0.444

From the complete question, we have the following parameters

<u>Canadians</u>

Sample size = 50
Mean = 4.6
Standard deviation = 2.9

<u>Americans</u>

Sample size = 60
Mean = 5.2
Standard deviation = 1.3

The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.

This is represented as:

$SE = \frac{\sigma}{\sqrt n}$

The standard error of the Canadian sample is:

$SE_1 = \frac{2.9}{\sqrt{50}}$

So, we have:

$SE_1 = 0.41$

The standard error of the American sample is:

$SE_2 = \frac{1.3}{\sqrt{60}}$

So, we have:

$SE_2 = 0.17$

The standard error of the difference of sample means is then calculated as:

$SE= \sqrt{SE_1^2 + SE_2^2}$

This gives

$SE= \sqrt{0.41^2 + 0.17^2}$

$SE= \sqrt{0.197}$

Take square roots

$SE= 0.444$

Hence, the standard error of the difference of sample means is 0.444

__________, which is an essential biological compound found in DNA and amino acids that make up proteins, occurs in the atmosphe

tamaranim1 [39]

Answer: Nitrogen; fixation

Explanation:

Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.

Fixation consists of two steps: cessation of normal life functions in the tissue (killing) and stabilization of the structure of the tissue (preservation). The goal of fixation is to preserve structure as faithfully as possible compared to the living state.

There is a need for a more sophisticated means of managing and tracking the complex movement of goods from place to place throug

saw5 [17]

The mechanism that can be used to manage and track inventory is a barcode system.

<h3>What is Inventory?</h3>

This refers to the stock-taking of goods and products in a given warehouse in order to keep records of them.

Hence, we can see that based on the need for more sophisticated means of inventory taking, we can see that the need of a barcode system is needed as tags would be given to the goods, for easier tracking.

Paradichlorobenzene, c6h4cl2 c 6 h 4 c l 2 , is a component of mothballs. A solution of 2. 00 g g in 22. 5 g g of cyclohexane bo

Nimfa-mama [501]

The value of kb of cyclohexane in the given question is; kb = 2.82 °C/m

<h3>Understanding Molality of a Solution</h3>

Molality of solution = (Number of moles of C₆H₄Cl₂)/(Mass of Cyclohexane)

Now;

Number of moles of C₆H₄Cl₂ = Mass/molar mass = 2g/147 g/mol

Number of moles of C₆H₄Cl₂ = 0.0136 mol

Molality of solution = 0.0136/(22.5 * 10⁻³ kg)

Molality of solution = 0.6 m

Now, to find kb for cyclohexane, we will use the formula;

T_b(solution) - T_b(solvent) = kb × molality of solution

Thus;

82.39 - 70 = kb * 0.6

kb = (82.39 - 70)/0.6

kb = 2.82 °C/m
