A medical researcher conjectures that smoking can result in the wrinkled skin around the eyes. The researcher recruited 25 smokers and 20 nonsmokers to take part in an observational study and found that the degree of wrinkled skin around the eyes out of 10 scales are given in below. Smokers Nonsmokers 10 4 8. 9. 4 4 8 9. 5 8 9. 1 7 8 7 8 8 5 4 5 7 8 10 7 1 2 3 1 9. 10 2 1 3 2 1. How do the smokers can be compared to the non-smokers based on above table? 2. Can you estimates the ratios of wrinkled skin? 3. Do you think that the above data and your conclusion are accurate? Use the level of significance equals to 0.05.

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.
