Solution Manual Mathematical Statistics With Applications 7th Edition Wackerly Chapter 1: What is Statistics? 1.1 a. Population: all generation X age US citizens (specifically, assign a ‘1’ to those who want to start their own business and a ‘0’ to those who do not, so that the population is the set of 1’s and 0’s). Objective: to estimate the proportion of generation X age US citizens who want to start their own business. b. Population: all healthy adults in the US. Objective: to estimate the true mean body temperature c. Population: single family dwelling units in the city. Objective: to estimate the true mean water consumption d. Population: all tires manufactured by the company for the specific year. Objective: to estimate the proportion of tires with unsafe tread. e. Population: all adult residents of the particular state. Objective: to estimate the proportion who favor a unicameral legislature. f. Population: times until recurrence for all people who have had a particular disease. Objective: to estimate the true average time until recurrence. g. Population: lifetime measurements for all resistors of this type. Objective: to estimate the true mean lifetime (in hours). 1.2 a.
