Community college instructors' salaries in one state are very low, so low that educators in that state regularly complain about their compensation. The national mean is
\( \$ 51,851 \), but instructors from Mississippi claim that the mean in their state is significantly lower. They survey a simple random sample of 46 colleges in the state and
calculate a mean salary of \( \$ 48,923 \) with a standard deviation of \( \$ 15,489 \). Test the instructors' claim at the 0.025 level of significance.
Step 3 of 3: Draw a conclusion and interpret the decision.

Math Essentials and How UpStudy Enhances Your Learning
Who Invented Math?
Math was less invented than found. Its roots are in prehistoric societies including Greece, Babylonia, and Egypt where early mathematical ideas including geometry, arithmetic, and simple number systems first found expression. While building on past contributions by others who came before, Euclid and Pythagoras were crucial in establishing mathematical theory during this age; today Carl Friedrich Gauss and Terence Tao continue to greatly enhance modern math.
What Does 'Mean' Mean in Math?
In math, the 'mean' is a type of average. To calculate the mean, you add all the numbers in a set together and divide by the number of values. This gives you a single number that represents the central tendency of the data. For example, if five students have scores of 8, 9, 5, 6, and 7, you add them up (35) and divide by 5, which gives a mean of 7. It’s an essential tool in statistics and helps summarize a set of data with just one number.
What Does 'Product' Mean in Math?
In math, the 'product' refers to the result you get when two or more numbers (called factors) are multiplied together. For example, the product of 2 and 3 is 6, since 2 × 3 = 6. The product is an essential concept in many areas of math, including algebra and geometry. It’s useful in everyday life too, such as when calculating the total cost of multiple items or determining the area of a rectangle.
