Do cat owners sleep better than those without cats? To help answer this question, a cat enthusiast obtained a random sample of 500 Canadians, each of whom answered two questions: 1. do you have a cat? (yes or no), 2. How well do you sleep? (good, neutral, bad). The dataset “CatSleep.xlsx” contains her findings. Find the probability that a randomly selected Canadian is a bad sleeper and a cat owner. Find the probability that a randomly selected Canadian is a neutral sleeper or a cat owner. Find the probability that a randomly selected non-cat owner is a bad sleeper. That is, find the probability that a randomly selected Canadian is a bad sleeper, given they are not a cat owner
If a particular shipment of thousands of aspirin tablets actually has a 44% rate of defects, what is the probability that a sample of 15 tablets contains two or more defective tablets?
A 10-year study conducted by the American heart Association provided data on how age, blood pressure, and smoking relate to the risk of strokes. Assume that the following data are from a portion of this study. Risk is interpreted as the probability (times 100) that the patient will have a stroke over the next 10-year period.

A well-known psychology graduate program claims that their Ph.D. graduates get higher-paying jobs than the national average. Last year's figures for salaries paid to all graduates with a psych Ph.D. on their first job showed a mean of $6.20 per hour. A random sample of 10 graduates from last year's class of psychology Ph.D.s showed the following hourly salaries for their first job: $5.40 $6.30 $7.20 $6.80 $6.40 $5.70 $5.80 $6.60 $6.70 $6.90 (a) What is the alternative hypothesis? (b) What is the null hypothesis? (c) What can you conclude about the psychology graduate program's claim? Use an alpha level = .052tailed. (d) What error might you be making by your conclusion in part (c)? (e) If you were only concerned with evaluating whether salaries increased, how would this effect the power of your experiment?
A study of 3000 people compared the rates of liver cancer between 2000 people who drank one or more cup of coffee per day and 1000 people who drank less coffee than that. Of the coffee drinkers, 21 got liver cancer, while of the people who didn’t drink coffee, 20 got liver cancer. Do a hypothesis test for the question: “Is there an association between coffee drinking and liver cancer?” Interpret your results. Does coffee drinking increase, decrease or not affect the probability of getting liver cancer?
Estimates from the American Diabetes Association suggest that 10% of the American population has diabetes. According to recent research,[1] the prevalence of smoking is 25.7% among individuals with diabetes, and 24.1% among individuals without diabetes. If a smoker is selected at random, what is the probability that the individual has diabetes? What is the probability that a non-smoking individual actually does not have diabetes?
