1. 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% condence interval for the average number of births per household in this study. Provide a correct interpretation of your interval
