The purpose of college is that you study and get good grades to get to university and have a high pay job and retire early and enjoy life
Answer:
5.89seconds
Explanation:
power is workdone over time, time is therefore workdone over power
(8.72*106)/(1.51*104)
=5.885
~5.89 seconds
Answer:
17x-8=11x+4
Add 8 to both sides:
17x=11x+12
Subtract 11 x from both sides:
6x=12
Divide both sides by 6:
x=2
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:
The standard error of the Canadian sample is:
So, we have:
The standard error of the American sample is:
So, we have:
The standard error of the difference of sample means is then calculated as:
This gives
Take square roots
Hence, the standard error of the difference of sample means is 0.444
