STAT 250 Study Guide - Final Guide: Food Desert, Confidence Interval, Summary Statistics
Document Summary
Stat 250 exam 3 name ----------------------------------------------: an investigator wants to determine if a new program aimed at reducing the overall number of pregnancies in a highly populated area is effective (reducing average births below 6 per household). In order to carry out the investigation, the investigator conducts a srs of 189 participants in the program and finds the average number of births is 4. 7 with a sample standard deviation of 0. 9 births. Construct a 95% confidence interval for the average number of births per household in this study. Provide a correct interpretation of your interval: recently there has been quite a bit of controversy about the lack of definitive knowledge about the adverse side effects associated with hormone based birth control usage. Suppose a researcher is interested in the effects of birth control in women aged 18-25 relevant to blood pressure.
