Every human starts puberty at a different time. Usually, all humans (boy and girls) experience puberty/adolesence between the ages of 12 and 18, but that is a broad range to go by. Also, according to statistics, girls usually mature faster than boys.

Is the ratio of boys to girls 2 to 3 the same as girls to boys 3 to 2?

Yes they are.


Are girls better at math than boys?

Its not about gender. I am in the top maths class just now, and there are the pretty much the same amount of boys as there are girls. It's about the individual person, && how hard they are willing to work.


There are twice as many girls as boys in a chemistry class If 50 percent of the girls and 80 percent of boys have finished the test what percent are still working on the test?

Still working on the test. At first glance you know that at least one third of the class is still working on it (half the girls are one third of the class). And since over half the boys have finished, you know the total remaining is less than half. You can figure it out using any numbers to set it up, but let's use 20 girls and 10 boys as the simplest. So 10 girls and 8 boys have finished for a total of 18, which leaves 12 still working on it. 12/30 is 6/15ths which is 2/5ths which is the same as 40%.


What is the directional and non-directional hypothesis testing?

In statistical hypothesis testing you have a null hypothesis against which you are testing an alternative. The hypothesis concerns one or more characteristics of the distribution. It is easier to illustrate the idea of directional and non-directional hypothesis. In studying the academic abilities of boys and girls the null hypothesis would be that boys and girls are equally able. One directional hypothesis would be that boys are more able. The non-directional alternative would be that there is a gender difference. You have no idea whether boys are more able or girls - only that they are not the same.


Two boys can paint a fence in 7 hours Two girls can paint the same fence in 5 hours In the unlikely event that they can work at the same pace together how long would the four people working togethe?
