In 1960, census results indicated that the age at which Canadian men first married had a mean of 23.3 years! It is widely suspected that young people today are waiting longer to get married. We want to find out if the mean age if first marriage has increased during the past (approximately) 50 years. a) Write down an appropriate hypothesis. b) We plan to test our hypothesis by selecting a random sample of 40 men who married for the first time last year. Do you think the necessary conditions for inference are satisfied? Explain c) The men in our sample married at an average age of 24.2 years with a standard deviation of 5.3 years. What is the P-value for this result? d) Explain (in this context) what the P-value means. e) What’s your conclusion?

Studies conducted in the 1970s indicated that the average age at which children take their first alcoholic drink is 14.6 years old. Sociologists believe that children are starting to drink at a younger age. A random sample of 169 young adults (18 years of age) is selected and the age at which each adult took their first alcoholic drink is recorded. The sample mean age was 13.3 years of age with a standard deviation of 5 years. For the problems...

(Mean: 1 sample)A survey had indicated that the average weight of men over 55 years of age with newly diagnosed heart disease was 90 kg. However, it is suspected that the average weight of such men is now somewhat lower. How large a sample would be necessary to test, at the 5% level of significance with a power of 90%, whether the average weight is unchanged versus the alternative that it has decreased from 90 to 85 kg with an...
