You can use the mean to answer some statistical questions: it is a measure of the central tendency of a set of data. However, it is no good in identifying the maximum value of a set of data, for example.
That depends on the question.
Yes
What is the use of statistical inference in technology?
There are different methods for comparing the mean, variance or standard error, distribution or other characteristics of populations. Without more specific information it is not possible to answer the question.
Use of statistical techniques in capital market?"
You know nothing about how to use statistical analysis to verify or test validity, do u.

you explain how to solve this question? If there is an equation that I can use will be appreciated. 70% of students answered question A correctly, 55% of students answered question B correctly, 20% of students answered neither question correctly. What is the percentage of students answered both question A and B correctly?
explain what you mean and maybe you question will be answerd.

this question is an American government question
Statistical tools are tool which are purposively make or are use for data collection and analysis in research methodology. E.g destriptive. mean. standard deviation. chi_square e.t.c
The research question is what your research is trying to explain/find answer. It generally attempts to find a way to relate your experiment with a target population (usually humankind).The statistical question deals with your specific experiment as in how your experiment affects your sample population. It is essentially what you are trying to determine.Example:A company has developed a new pesticide designed to control pine beetles in the coniferous forests, but the law requires that it's effect on fish populations is tested first before it can be released. Thus, we'll test the pesticide on the mortality of a chose fish species in our lab.Research Question: To what extent will the use of the new pesticide harm native fish poplulations?Statistical Question: How does the pesticide, when introduced to the water source, affect the fish we have in our lab?
