He blew the problem out of proportion.
The professor's answer was all out of proportion to the question at hand. What proportion is the model?
Assuming that the question is find x in x5=1610; the answer is 4.378901
It is not possible to answer the question since there is no information as to whether the relationship between x and y is one of direct proportion, inverse proportion or something else.
A percent is simply a proportion out of 100.
100/62 is the appropriate proportion.
To do a proportion all you have to do is find the equivilent fraction. For example: 4/7=12/221
Yes, they do exist. And the question is ...
To calculate the standard error for a proportion, you can use the formula: [ SE = \sqrt{\frac{p(1 - p)}{n}} ] where (p) is the sample proportion and (n) is the sample size. If the proportion is not given in your question, you'll need to specify a value for (p) to compute the standard error. For a sample size of 25, substitute that value into the formula along with the specific proportion to find the standard error.
Multiply 0.1 by 400 to get 40. This is how you find 10% of 400 without using proportion.
