Different kinds of companies cmpensate their key employees in different ways. Established companies may pay higher salaries, while new companies may offer stock options that will be valuable if the company succeeds. Do high-tech companies tend to offer stock options more often than other companies? One study looked at a random sample of 200 companies. Of these, 85 were listed in the Directory of Public High Technology Corporations and 115 were not listed. Treat these two groups as SRS's of high-tech and non-high-tech companies. 72 of the high-tech companies and 68 of the non-high-tech companies offered incentive stock options to key employees. A) Is there evidence that a higher proportion of high-tech companies offer stock options? (use a=.05) z =_______________ P-value +_________________ Conclusion: a or b a) There is significant evidence that a higher proportion of high-tech companies offer stock options. b) There is no evidence that a higher proportion of high-tech companies offer…

An insurance company is thinking about offering discounts on its life insurance policies to nonsmokers. As part of its analysis, the company randomly selects 200 men who are 60 years old and ask them if they smoke at least one pack of cigarettes per day and if they have ever suffered from heart disease. 10 out of the 38 smokers had suffered from some type of heart disease and 12 out of 150 nonsmokers had suffered from some type of heart disease. Can we conclude at the 5% level of significance that smokers have a higher incidence of heart disease than nonsmokers? (Don't hand writing solution)
