If n*p is greater than or equal to 5 AND n*q is greater than or equal to 5, you can use a normal distribution as an estimate for the binomial distribution. Recall, n is the number of trials, p is the probability of success of a trial, and q is 1-p.

When do you use a normal distribution?
When studying the sum (or average) of a large number of independent variables. A large number is necessary for the Central Limit Theorem to kick in - unless the variables themselves were normally distributed. Independence is critical. If they are not, normality may not be assumed.
What leads to the development of a hypothesis?
You may form a hypothesis about an every day event.
What is debt hypothesis?
Debt hypothesis is the hypothesis in which a person may go into or get out of debt. In other words, it's a theory an individual may come up with to measure ways to avoid or get out of being in debt.
A normal probability plot may be used to assess the assumption of normality for a particular batch of data true or false?
True.
What is the difference between forming a hypothesis and testing a hypothesis?
forming a hypothesis is when you come up with an educated guess.. what you think it may be . testing a hypothesis is when you're testing to see if someone else's guess is right.

Will the normality of an NaOH solution increase or decrease if the solution is exposed to air for prolonged periods?
The normality of an NaOH solution will remain the same if exposed to air for prolonged periods because normality is a measure of concentration. However, the concentration of the solution may change if water evaporates from the solution, leading to an increase in the normality.
Define Phat in statistics?
p-hat is the 'proportion in your sample.' It may be given as a percentage, a proportion or you will have to figure it out as a fraction (proportion).
Does a hypothesis have to be right?
A hypothesis is an educated guess as what you think will happen in an experiment. A hypothesis is what you think may happen- so it may or may not be right. After dealing with the experiment, you must create a conclusion. In the conclusion, describe what actually happened and why or why not your hypothesis proved to be true or not.
Does a scientific hypothesis have to be right?

True.
You may use the information in your conclusion to write a revised hypothesis?
Yes, you may use the information in your conclusion to write a revised hypothesis.
