If you don’t have the data, then you need to decide if the problem describes collecting data from one group or from two groups. If the problem talks about "find the value", "estimate the" or "find the interval", then you are doing a confidence interval.

The bank assets (in billions of Australia dollars (AUD)) of the Reserve Bank of Australia (RBA) for the time period of March 2007 through March 2013 are contained in Example \PageIndex11 ("B1 assets of," 2013).

The difference between a voluntary response survey and a scientific study is that in a scientific study the researchers ask the individuals to be involved, while in a voluntary response survey the individuals become involved on their own choosing.

The focus of this chapter is a distribution known as the normal distribution, though realize that there are many other distributions that exist. A few others are examined in future chapters.

Testing the claim that a diet works by looking at the weight before and after subjects are on the diet.

The process is to draw the line through the data and then find the distances from a point to the line, which are called the residuals. The regression line is the line that makes the square of the residuals as small as possible, so the regression line is also sometimes called the least squares line.

There are two branches of inferential statistics: hypothesis testing and confidence intervals. Definition \PageIndex1 Hypothesis Testing: making a decision about a parameter(s) based on a statistic(s). Definition \PageIndex2 Confidence Interval: estimating a parameter(s) based on a statistic(s).

Once you have the hypothesis, you collect data and use the data to make a determination to see if there is enough evidence to show that the hypothesis is true. However, in hypothesis testing you actually assume something else is true, and then you look at your data to see how likely it is to get an event that your data demonstrates with that assumption.

Variable – the height of the plant (Note: it is not the average height since you cannot measure an average – it is calculated from data.) This is quantitative data since you will have a number.
