To compare the average amount of time that canadians and americans spend commuting, a researcher collects a sample of canadians and americans. The canadians spend an average of hours a week commuting, with a standard deviation hours. The mean and standard deviation for the sample of americans is hours and hours, respectively. The standard error of the difference of sample means is:.
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

C. XZ = 9√2cm
What is an Isosceles Triangle?An isosceles triangle has two equal base angles of the same angle measure.The sides opposite to the two equal base angle of an isosceles triangle are congruent (equal in length).A right isosceles triangle can be solved using the Pythagorean Theorem given as: c² = a² + b², where a and b are the two smaller equal lengths, and c is the hypotenuse or longest side.Thus, based on the properties of an isosceles triangles and the Pythagorean Theorem, the statements that will be true regarding ΔXYZ are:

Marian traveled at an average speed of 65 mi/h for 15 hours. Kristen travels at an average speed of 50 mi/h. How many hours does it take kristen to travel the same distance marian traveled? express your answer as a decimal to the nearest tenth.
The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.
The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:
speed = distance / time
Therefore,
distance = time × speed
distance = 15 × 65
distance = 975 miles
Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:
speed = distance / time
time = distance / speed
time = 975 / 50
time = 19.5 hours

In general, an organism will be more likely to develop phobias of dangers faced during natural circumstances.
Phobia is an unjustified or pathological fear of situations or circumstances that are not dangerous and that most people do not find bothersome. Fear is a natural reaction or an adaptive experience to situations or objects that imply a real danger.When this fear occurs before natural circumstances that do not pose a real danger, then we find this fear is no longer adaptive is what we call a phobia.
Therefore, we can conclude that an organism will be more likely to develop phobias of dangers faced during natural circumstances.
