Concept explainers

Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

- A Read aloud V Draw Highlight II. A random sampie of 30 TOur-member families visiting Disneyworld was selected, and the average amount spent by these families on their Disneyworld visit was $825.75. The population standard deviation is $98.25. Find the 90% confidence interval for the true population mean. Express the interval endpoints to the nearest cent. 12. In a sample of 600 Canadians, 265 say they would rather retire in the US than in Canada. Calculate the 95% confidence interval for the true proportion of Canadians who would rather retire in the US. 13. Use Z-scores to determine which is a better relative golf score (remember that in golf, lower scores are better): Shooting a 75 in Tournament A where the mean score is 73 and the standard deviation is 3.4; or shooting a 76 in Tournament B where the mean score is 74 and the standard deviation is 3.6 .
