A medical researcher conjectures that smoking can result in the wrinkled skin around the eyes. The researcher recruited 150 smokers and 250 nonsmokers to take part in an observational study and found that 95 of the smokers and 105 of the nonsmokers were seen to have prominent wrinkles around the eyes (based on a standardized wrinkle score administered by a person who did not know if the subject smoked or not). Create a 90% confidence interval to compare the prominent wrinkles for the smokers and the non-smokers. (consider smokers minus non-smokers) Round your answers to two decimal places, if necessary. If your answer is a negative number, enter "minus" sign. Write your answer in the form of LowerLimit, UpperLimit (separate the values using comma)
