The standard error of the difference of sample means is 0.444
From the complete question, we have the following parameters
Canadians
Sample size = 50Mean = 4.6Standard deviation = 2.9Americans
Sample size = 60Mean = 5.2Standard deviation = 1.3The standard error of a sample is the quotient of the standard deviation and the square root of the sample size.
This is represented as:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
The standard error of the Canadian sample is:
[tex]SE_1 = \frac{2.9}{\sqrt{50}}[/tex]
So, we have:
[tex]SE_1 = 0.41[/tex]
The standard error of the American sample is:
[tex]SE_2 = \frac{1.3}{\sqrt{60}}[/tex]
So, we have:
[tex]SE_2 = 0.17[/tex]
The standard error of the difference of sample means is then calculated as:
[tex]SE= \sqrt{SE_1^2 + SE_2^2}[/tex]
This gives
[tex]SE= \sqrt{0.41^2 + 0.17^2}[/tex]
[tex]SE= \sqrt{0.197}[/tex]
Take square roots
[tex]SE= 0.444[/tex]
Hence, the standard error of the difference of sample means is 0.444

what is the molarity of a solution prepared by dissolving 54.3 g of ca(no3)2 to form 355 ml of the solution?
Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;

Explanation:
the table below shows the ages of houses to the nearest year in a neighborhood. using the age of the houses as the random variable, x, which graph shows the probability distribution, px(x), of a randomly chosen house?
Probability distributions are used to represent data and their probabilities
The table entry is given as:
Age of House Number of Houses
1 15
2 20
3 25
4 30
Start by calculating the probability of selecting a house that has a certain age.
This is calculated as:
[tex]Pr =\frac{Number\ of\ house}{Total\ number\ of\ house}[/tex]
So, we have:
[tex]P(1) = \frac{15}{90} = 0.17[/tex]
[tex]P(2) = \frac{20}{90} = 0.22[/tex]
[tex]P(3) = \frac{25}{90} = 0.28[/tex]
[tex]P(4) = \frac{30}{90} = 0.33[/tex]
This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.
