In the Winona Wildcats study presented in Chapter 14 (question 17), Pete Thames, the team's general manager, has decided to use a stratified sample. One sample group includes only those who attended Wildcats games during the past two years. The other sample group represents nonattenders. The Wildcats hope to draw fans from Winona and surrounding areas, which have a combined population of 144,000. 

a. What proportion of those included in the sample should be in the stratum of nonattenders, assuming that a directly proportional method of stratification will be used?

b. What is the actual number of people in the nonattender sample?
